How is gestational age calculated? Calculation of gestational age, methods for determining the period by week, calculator. Calculation on the last day of menstruation

Gestational age- one of the main components that a gynecologist needs to know about for the proper management of pregnancy. After all, on the basis of this, the doctor will prescribe the necessary examinations, tests, planned ultrasound, monitor intrauterine growth and development of the fetus, during the identification of possible violations. In addition, the determination of the term allows you to fairly accurately calculate the date of birth and the date of maternity leave. The woman herself needs to know the gestational age in order to mentally prepare for childbirth, to have time to prepare a room or a corner for the future baby, to purchase all the necessary accessories and clothes for him.

In the article, we will consider how to determine the gestational age.

Calculate by monthly

The gynecologist first of all asks a woman who has come to register at the antenatal clinic the question of when her last menstruation began. It is from this date that he begins to keep a record, despite the fact that fertilization has not yet occurred. It is known that the fertilization of the egg occurs on the day of ovulation, which occurs in the middle of the menstrual cycle. This method of determining the gestational age is called "obstetric".

An online calculator will help determine the term:

How to determine the gestational age by the date of conception

It is known that conception occurs only during ovulation within a day after the release of the egg from the follicle. And the viability of spermatozoa in the female genital tract is up to 3 days. It turns out that the date of sexual intercourse does not always coincide with the date of conception.

Ovulation occurs in the middle of the menstrual cycle. A woman who monitors her menstrual cycle can quite accurately calculate the onset of ovulation in herself. In addition, many at this time have characteristic signs: aching pains in the lower abdomen, breast swelling, irritability, copious vaginal discharge, increased sexual desire.

It is worth noting that only those women who have a regular menstrual cycle can determine the gestational age by the date of conception.

How to calculate by ultrasound

It is possible to find out the gestational age by the results of an ultrasound examination (ultrasound). It is determined according to the size of the fetus. The first ultrasound of the expectant mother is performed at 12-14 weeks, but it is still impossible to determine the exact date, since the development of the fetus in each woman occurs individually. Finding out the age of the fetus by ultrasound with an accuracy of one day is possible only in the first weeks after conception.

Determination of the entrance of the examination by a gynecologist

A gynecologist can determine a woman's gestational age by the size of her uterus during a pelvic exam. At 5-6 weeks, the size of the uterus can be compared with a chicken egg, at 8 weeks - with a goose egg. Later, it will be more difficult to determine how many weeks a woman has by the size of her uterus.

Find out the date by the first movement of the fetus

A woman begins to feel fetal movements in the first pregnancy at 20 weeks, in the second - at 18 weeks. But this method does not always allow you to set a time limit, since some expectant mothers may feel the first fetal movements earlier or later than the indicated weeks - some, due to the structural features of the body, cannot feel the fetal movements, others confuse the work of the intestines (increased flatulence) with movements.

Determine by hCG

Human chorionic gonadotropin (hCG)- one of the most important indicators indicating the onset of pregnancy and its normal development. The hormone begins to be produced in the female body after the implantation of the embryo into the wall of the uterus. HCG level in the blood allows you to find out the approximate age of the fetus. With multiple pregnancy, the level of the hormone in the blood increases in proportion to the number of fetuses.

Few people know that the gestational age is classified into two types: obstetric and embryonic (true, real). For both, there are their own, very easy ways of counting, which are available to every expectant mother. Which one is actually true, how to calculate both, and what are the features of each of them - the answers to these questions can be found below.

What does obstetric gestation mean?

The obstetric period (a method for determining pregnancy) is the time from the first day of the last menstruation before the conception occurred. Such a definition is quite logical, because the countdown starts from the day when the egg began to mature, which was subsequently fertilized by the male seed.

This method is universal, but its significant drawback is that the individual characteristics of a woman are not taken into account. The universality of the method lies in the fact that exactly 280 days (40 weeks) are always added to the first day of the last menstruation.

This is a rather old way of determining the term, which women have been using for decades. It was determined by the people - especially curious women and men once noticed that exactly 280 days pass between the first day of the last menstruation and the birth of a child. Over time, this technique has become firmly entrenched in obstetric practice.

Traditionally, the obstetric period is longer than the embryonic one by 2 (sometimes 3) weeks. Why this difference occurs is easy to understand: the average duration of the female menstrual cycle is 28 days, and ovulation - the day the follicle ruptures and the egg is released into the fallopian tubes - usually occurs in the middle of the cycle, i.e. on the 14th day.

The truth of this method may cause a number of doubts: what about women who have a long (30-35 days) or short (21-25 days) cycle? What about early or late ovulation? Based on these and many other questions and nuances, we can conclude that the obstetric method, although it is a fairly popular way to determine the term, the most informative and accurate is the establishment of the date of birth using ultrasound.

An obstetric calculation is called such precisely because the doctor tracks the entire pregnancy of a woman, based precisely on the day the last menstruation begins. The reason for this is simple: a woman can indicate this date with 100% certainty, while the moment and date of the “key” sexual intercourse, and even more so, fertilization, remain a mystery to both the expectant mother and the gynecologist.

How to calculate the obstetric gestational age yourself?

It is easy for women who keep a personal calendar and mark the days of menstruation to independently calculate the obstetric period. So, when confirming pregnancy, this can be easily done at home by looking at the calendar on the first day of the last menstruation.

There are two ways to calculate the term, and everyone can choose the most convenient for themselves:

  1. 280 days (40 weeks) is 9 months and 7 days. So, according to the first method, you can calculate the period by adding 9 months and 7 days to the first day of the last menstruation. For example, the last menstruation before the fertilization occurred began on December 10th. We add 9 months - we get September 10th, plus another 7 days - September 17th. This is the expected date of birth.
  2. The actual duration of childbearing- 9 months is three less than the total number of months in a year (12). Therefore, you can simply subtract 3 months from the first day of the last period and also add 7 days. According to the above example, we calculate that December is the 12th month in a row. Therefore 12-3=9 and the 9th month is September. 10+7=17.

That's the whole simple calculation.

How to calculate the real (embryonic) gestational age?

The embryonic (true, real) gestational age seems much more logical to many. It is calculated from the day when the conception occurred, i.e. since ovulation. However, even here there are pitfalls: the calculation takes into account the generally accepted standard value of the middle of the cycle - 14 days. That is, if a woman ovulates on the 12-18th day, the true term is not at all true.

It also does not take into account the fact that fertilization does not always happen exactly at the moment when the egg has left the follicle. In medical practice, unique cases of conception have been recorded that occurred a few days after the release of the egg, or even in the last days of menstruation. There are situations when a woman had unprotected sex, a few days later she had her period, and after they ended, she became pregnant. All these and other features take into account only one way to determine the term - ultrasound, but even he cannot be trusted 100%.

  1. According to the above methods, determine the obstetric period and add 14 days.
  2. Add 14 days to the first day of the last menstruation - this is the approximate date of ovulation (and for girls with a cycle of 28 days - the exact one), and then another 9 months.

It is even better and easier if the girl planned the pregnancy and knows exactly the day of ovulation. Then the total duration of pregnancy (266-280 days) is added to this day. You can use the calendar and calculate a more accurate figure.

How is the obstetric term different from the embryonic?

Both of these methods of determining the term can be considered relatively reliable. The main differences have already been discussed above, and can only be summarized:

  • The obstetric gestation period is counted from the beginning of the maturation of the egg, the embryonic - from the moment of the fusion of the egg and sperm and the creation of the embryo.
  • The difference between the two terms is usually 2-3 weeks.
  • At the first visit to the doctor and registration, it will be precisely the obstetric gestational age that will be determined, and the specialist will be guided by it for all 9 months.

Both of these methods of determining the date of birth are considered conditionally accurate, since a discrepancy of several days or even weeks can be due to a number of reasons. The more carefully a woman monitors her health, her cycle and carefully prepares for pregnancy, the higher the chance of the most accurate determination of the term. In addition, ultrasound data, which are the most accurate and scientifically based, are necessarily taken into account.

1 week pregnant

In modern obstetrics, it is customary to count the gestational age from the first day of menstruation preceding conception. And we will do the same in the Pregnancy Calendar for 7th.ru. It turns out that conception has not yet occurred at the 1st week of pregnancy, the body of the expectant mother is only preparing for it - menstruation passes and ends, the egg matures in the ovary. After about 12-14 days, she will come out of the ovary - ovulation will occur - and, with a good combination of circumstances, she will meet with the sperm. This will give rise to a new life.

Since, in fact, fertilization has not yet occurred, there are no signs of pregnancy at week 1 - so far they simply cannot be. But during this period, a woman is completely sure of her desire to be a mother, she feels a certain upsurge and a surge of strength. It's all about hormones - her body is slowly preparing for the upcoming ovulation.

Pregnancy planning is very milestone where both parents need to take care of their health and reconsider their attitude to addictions. After all, the chance of pregnancy and birth depends on how healthy the parents are. healthy baby. During this period, it is highly undesirable for one or both parents to drink alcohol, take drugs or medications that can affect the development of the fetus and the course of pregnancy. If you've wanted to quit smoking for a long time, now is the time. The chance of conception for fathers who smoke is much lower than for non-smokers. The reason for this is the detrimental effect of nicotine on the number of spermatozoa and their motility.

At 1 week of pregnancy, the expectant mother needs to eat right, walk a lot in the fresh air, do physical exercises and take prenatal vitamins, which contain all the necessary substances, including folic acid, which reduces the risk of neural tube defects in the fetus during pregnancy. Also, the expectant mother should avoid x-ray exposure of the abdominal cavity, which can affect the conception and health of the unborn baby.

2 weeks pregnant

Gynecologists begin to keep a record of pregnancy from the beginning of the last menstruation, that is, from the moment when fertilization has not actually occurred yet. At the 2nd week of pregnancy, the woman’s body is only preparing for the meeting of the egg and sperm: at this time, the egg matures and ovulation occurs, but there is no pregnancy itself from a medical point of view. If a woman is planning a pregnancy, now she does not need a pregnancy test, but an ovulation test. Ultrasound is not done in the second week of pregnancy (unless it is necessary to accurately determine ovulation).

In the second week of pregnancy, the level of hormones increases, which will keep the fetus. During the period of ovulation, a woman feels very well: menstruation has passed and the weakness associated with it too. No specific sensations in the body of a woman yet occur, there are no signs of pregnancy in the second obstetric week.

If you are planning a pregnancy, gynecologists recommend that you do not douche before intercourse and do not use intimate hygiene cosmetics that can change the acidic environment in the vagina, just take a shower and tune in for a good result. Do not forget about vitamins for pregnant women, completely refuse to take alcohol, stop smoking and avoid stress.

3 weeks pregnant

According to the obstetric calendar, the third week of pregnancy corresponds to the first week of pregnancy from conception. At this time, the mature egg migrates into the uterine cavity - when passing through the fallopian tube, spermatozoa begin to attack it. Millions of sperm cells surround the egg and compete for the right to fertilize. But only one of them will penetrate the oocyte membrane and unite with it, giving rise to a new life. After the penetration of the sperm into the egg, a kind of chemical reaction is triggered, and the shell of the egg becomes impermeable to the rest of the sperm.

30 hours after the fusion of the sperm and egg, the zygote divides into cells within itself. Having reached the uterus, the zygote begins to settle in a new place. It is during this period that the placenta begins to form, which protects and nourishes the fetus throughout the pregnancy until childbirth. The embryo still does not look like a child at all, while it is only a set of cells, 0.150 mm in size, but it already has all the genetic material received from its parents - it has 23 pairs of chromosomes. By the way, 3 obstetric week pregnancy - period when a fertilized egg begins its active division, and at this moment (if the parents have a genetic predisposition) a multiple pregnancy may begin to develop.

Ultrasound at 3 weeks pregnant can show exactly where the fertilized egg has attached. At this stage, your healthcare provider can determine whether the pregnancy is normal or ectopic. An ectopic pregnancy is a life-threatening future mother pathology of pregnancy, in which the attachment of a fertilized egg does not occur in the uterine cavity, but in the fallopian tube, ovary, or even in the abdominal cavity. Woman diagnosed with ectopic pregnancy"is subject to immediate hospitalization for further treatment and surgery.

4 weeks pregnant

So it's 4 weeks pregnant. What is happening at this stage? Firstly, a fetal egg attached to the wall of the uterus can now be safely called an embryo. True, it still does not look like a little man at all, rather, it resembles a flat disk, which consists of three layers (germ layers). Each layer in the process of growth and development of the embryo is converted into internal organs. Cells of the inner layer (endodermis) - the future digestive tract, liver, pancreas and thyroid glands, organs of the respiratory system of your baby. The cells of the middle layer (mesoderm) will form the bone skeleton, connective and muscle tissue, circulatory and excretory systems, and organs of the reproductive system. From the outer layer (ectoderm), extraembryonic organs are formed - the yolk sac, the chorion and the amniotic membrane of the fetus. These organs perform the protective, nutritional and respiratory functions of the fetus during pregnancy. At this stage of pregnancy, the embryo is deep inside the uterus and grows relentlessly. By the end of the fourth week, blastogenesis is completed - the initial stage of intrauterine development of the embryo. At 4 weeks pregnant, the embryo is approximately 0.36 mm long and 1 mm wide - like a small poppy seed.

In the fourth week, not only the baby is actively growing, but also the placenta, without which the development of pregnancy and the survival of the fetus would be impossible. Thanks to the placenta, the embryo receives all the necessary nutrients from the mother's body, with her help it breathes. Placentation is a long process that will be completed by the 12th week of pregnancy.

At this time, the expectant mother may begin to recognize the first signs of pregnancy. The most classic is a delay in menstruation. If you have a delay of at least one day, you can take a pregnancy test or donate blood for hCG. During a gynecological examination, pregnancy early dates quite difficult to determine, the results can be quite ambiguous. Ultrasound at 4 weeks of gestation is also still uninformative, but it can help to recognize an ectopic pregnancy and make a correct diagnosis.

5 weeks pregnant

The 5th week of pregnancy has come. The embryo has reached the size of a small sesame seed, the laying of all its systems and internal organs continues. During this period, it is especially important for the expectant mother to monitor her diet and take vitamins for pregnant women, containing all the necessary complex of substances, including folic acid (vitamin B9), which reduces the risk of developing fetal neural tube defects. During this period, it is highly undesirable to take alcohol or narcotic substances, as well as medicines that can harm the health of the unborn baby or even terminate the pregnancy.

At week 5, the signs of pregnancy are almost invisible, but the expectant mother already feels her unusual condition. During this period, the hormonal background of a woman undergoes strong changes, causing a quick change in mood, tearfulness and excessive emotionality. Also, at a period of 5 weeks of pregnancy, the expectant mother may be disturbed by fatigue and general malaise. Many women begin to experience painful bouts of nausea and vomiting in the morning - early toxemia of pregnant women, which are joined by headaches, sensitivity to smells and tastes. Perhaps the appearance of such a symptom as frequent urination during pregnancy.

5 obstetric week of pregnancy is an anxious time for many expectant mothers, especially those who were planning a pregnancy. Miscarriage is not uncommon in early pregnancy, especially if the woman is at risk or has experienced severe stress or trauma. Risk factors for non-developing pregnancy or miscarriage usually include: endocrine or genetic disorders, age over 35 years, gynecological diseases, unhealthy lifestyle, sexual infections, two or more miscarriages in the past. If there is reason for alarm (for example, pain in the lower abdomen during pregnancy, bleeding from the vagina, temperature) - immediately consult a doctor for all necessary examinations and hospitalization!

6 weeks pregnant

Almost half of the first trimester is behind you, because you are already 6 weeks pregnant. The fruit has reached the size of a pomegranate seed and continues to grow actively. Its internal organs are actively developing and the most important systems of the body are being improved. An ultrasound at the 6th week of pregnancy already shows very clearly where the embryo is located. Approximately at this time, the face is formed: the beginnings of the eyes, nose appear, the future chin, cheeks, ear canals are drawn. For a period of 6 weeks, you can listen to the heartbeat of the embryo, and after a while you can find out its frequency.

With the restructuring of the hormonal background of the expectant mother, important changes occur in her body. The uterus of a pregnant woman increases in size, its shape, reactivity, consistency changes, blood flow increases. The vaginal mucosa also becomes full-blooded, glycogen accumulates in it. Normal discharge at the 6th week of pregnancy is milky or transparent, homogeneous in consistency and without an unpleasant odor. If the discharge from the vagina has a yellow or green tint, you should immediately consult a doctor for the diagnosis and treatment of infectious diseases. You should also contact immediately medical care if you notice brown or bloody discharge - this may be a sign of a threatened abortion.

Do you have a stomach ache at 6 weeks pregnant? Don't delay your visit to the doctor! Unfortunately, early miscarriage is not uncommon. If you are at risk (your previous pregnancies ended in spontaneous termination, your lifestyle cannot be called correct, you are over 35 years old, there is a predisposition to genetic disorders, endocrine or gynecological diseases, infections, etc.), it is necessary to strengthen control over the course pregnancy and timely examinations.

7 weeks pregnant

The 7th week of pregnancy has come. The development and growth of the embryo continues, the most basic parts of the brain have formed, the nervous and cardiovascular systems are improving, the limbs and sex glands are slowly developing. Ultrasound at the 7th week of pregnancy will determine the stage of development of the fetus and its activity, and with the help of a special sensor, the doctor can listen to the heartbeat of a little man.

Many expectant mothers complain of headaches during pregnancy, especially in the early stages. This may be due to hormonal changes occurring in a woman's body, lack of oxygen, excessive exercise, stress. Even malnutrition pregnant woman and substances entering the body can provoke a headache. To diagnose and solve the problem, consult a doctor, do not self-medicate. Uncontrolled use of medications during pregnancy can cause serious damage to health and Negative influence on fetal development.

To prevent headaches, expectant mothers need to rest more often, avoid noisy and stuffy places, stressful situations, loud sound and very bright light, do not overeat, do exercises for pregnant women and spend more time outdoors. In severe attacks, turn off all sources of sound and light (including gadgets), drink a glass of cool still water, apply a wet compress to the forehead and take a horizontal position. If possible, ask your husband or someone close to give you a relaxing head and neck massage.

8 weeks pregnant

The 8th week of pregnancy is the best time to register in the antenatal clinic. During the initial visit, all important examinations of the expectant mother are carried out: the gynecologist will measure the pelvis and weight of the woman, conduct an examination on the chair, take a smear for infections, assess the condition of the cervix and issue directions for blood and urine tests. if you did not have time to do it earlier (for example, to clarify the pregnancy). Screening of the first trimester is carried out a little later - at 11-13 weeks of pregnancy.

At a period of 8 weeks of pregnancy, the stomach of the expectant mother may periodically ache: some women note slight uterine contractions (early training contractions) and unpleasant pain associated with stretching of the ligaments that hold the growing uterus. Pulling pains in the lower abdomen are a serious reason to see a doctor, as their appearance may indicate a threat of abortion!

At this stage, the expectant mother has already enlarged her breasts, and under the influence of the hormone prolactin, the glands responsible for the production of mother's milk begin to grow. From the 8th week, the cervix softens, and the mucous membrane of the cervical canal produces a cervical secret. The mucus accumulates and becomes thick, forming a plug and blocking the path of any infection from the vagina, thereby protecting the growing fetus. By the way, the passage of a cork from the cervical canal is one of the harbingers of an impending birth.

The 8th obstetric week of pregnancy is the period when the fetus forms the genital organs and produces the hormones necessary for their proper functioning. Right now, the optic nerve begins to emerge in your future baby, muscle tissue and bones continue their active development, olfactory receptors are born in the small nose, and taste buds on the tongue. The fetus at the 8th week of pregnancy has reached the size of a small grape and already weighs about 0.25 g.

9 weeks pregnant

The 3rd month of pregnancy has begun. At this stage, the figure of expectant mothers changes: at the 9th week of pregnancy, the stomach increases slightly, the breasts continue to grow, the pregnant woman notes special sensitivity and soreness of the nipples, some women may have a little colostrum at this time. Bloating, discomfort in the intestines , stool disorders, morning sickness in a pregnant woman, frequent urination are standard phenomena at week 9.

Allocations at the 9th week of pregnancy during this period are usually unremarkable, but the expectant mother needs to monitor their changes. Bloody or brown discharge from the vagina may indicate the need for urgent hospitalization to rule out the possibility of abortion. If you notice suspicious discharge of a yellowish, greenish hue, with an unpleasant odor, curdled, flaky or other atypical consistency, it makes sense to immediately consult a doctor. Any sexual infection in your position is a great danger to the life and health of the fetus. In no case do not self-medicate, entrust your health to specialists!

The fetus at the 9th week of pregnancy is actively growing, it has already got rid of the gills, and its tail will disappear very soon. The arched body of the baby is slowly taking on a human appearance, internal organs are developing, and life support systems are being established. To more accurately assess the condition of the fetus and its development, your doctor may prescribe an ultrasound at 9 weeks of pregnancy.

10 weeks pregnant

The 10th week of pregnancy has come. The belly of the expectant mother continues to grow, the chest - to pour and ache. Active hormonal changes in a woman's body provoke early toxicosis. Nausea and recurrent vomiting is accompanied by other sensations - drowsiness, fatigue, distraction, headaches. Also, the expectant mother may experience mood swings, irritability and emotional instability. Dark spots during pregnancy - another small "surprise" awaiting a woman in the early stages. However, experts say there is no reason to worry: hyperpigmentation of the skin disappears soon after the onset of childbirth. Expectant mothers are advised to stay in the sun with great care and use special sunscreens.

The 10th week of a woman's pregnancy is the time to update her wardrobe and switch to more comfortable clothes. Habitual jeans, tight skirts are not recommended, as they can put pressure on the stomach, which is highly undesirable. Comfortable and beautiful clothes for pregnant women - what you need. If you have big breasts, perhaps right now you will need to wear special underwear that will support the bust without exerting pressure and without disturbing blood circulation. Even if you have small breasts, get a nursing bra - you will appreciate its convenience.

At the 10th week of pregnancy, the fetus does not stop growing for a second. He has already reached the size of a small strawberry and more and more like a man. The organs of vision and hearing are formed, the rudiments of future teeth are born. At this time, the baby has full-fledged arms and legs, and small fingers are able to clench into a fist.

11 weeks pregnant

The first trimester continues. At the 11th week of pregnancy, the belly of the expectant mother continues to grow slowly, the uterus increases in size, the mammary glands become rough, the nipples become even more sensitive. In the woman's body, there is an increase in metabolism associated with the growing need for the fetus in nutrients. Some pregnant women notice the appearance of sweating during this period, as well as a constant feeling of thirst. Right now, most mothers have brittle nails, and their hair is dull and prone to falling out. The skin during pregnancy also undergoes changes: the work of the sebaceous glands intensifies, thereby causing the appearance of unwanted oily sheen, acne and pore enlargement.

In some pregnant women at week 11, the opposite picture is observed: hormones favorably affect the condition of hair, skin and nails. This difference is explained individual characteristics body, the nutrition of the pregnant woman during this period is of considerable importance. Correctly selected vitamins for pregnant women, as well as various cosmetic procedures not prohibited by your doctor.

On term 11 obstetric weeks the little man growing inside you has a sense of smell: he already smells the food you eat. The kid responds to his mother's sudden movements and covers his face with his hands, stretches and is active. At the 11th week of pregnancy, the fetus can roll over 360 degrees and push off the walls of the uterus, only the expectant mother does not yet feel his movements - this will happen later.

11 weeks pregnant is when your healthcare provider may schedule your first screening. This is necessary to assess the development of the fetus, identify pathologies (such as Down syndrome, Patau syndrome, fetal neural tube defect, etc.) and the course of your pregnancy in general. Ultrasound at 11 weeks of gestation is not a mandatory procedure, some pregnant women refuse to perform it, however, obstetrician-gynecologists, geneticists and neonatologists strongly recommend not to avoid this study.

12 weeks pregnant

The 12th week of pregnancy is a relatively quiet time for the expectant mother. During this period, most women stop early toxicosis, the general condition of the body improves. The belly at the 12th week of pregnancy grows with the uterus, it is not yet so noticeable to others and does not cause any inconvenience to the woman in position. The pregnant uterus rises a little higher and stops putting pressure on bladder, however, begins to put pressure on the intestines. For this reason, constipation occurs in pregnant women, as well as flatulence and discomfort in the abdomen. At this stage, many mothers note an improvement in appetite and begin to eat "for two", which is highly undesirable: excess weight during pregnancy can complicate the course of childbirth, as well as the postpartum period.

At the 12th week of pregnancy - the period of prenatal screening, which includes ultrasound and a biochemical analysis of the mother's blood. The purpose of this study is to assess the course of pregnancy and fetal development. It is during this period that it is possible to recognize the presence of chromosomal pathologies and genetic diseases in the fetus (for example, a fetal neural tube defect, Down syndrome), deformation or absence of organs, limbs. For a more accurate diagnosis of ultrasound at the 12th week of pregnancy, a transvaginal method is performed.

A child at the 12th week of pregnancy has reached the size of a small passionfruit fruit and weighs approximately 9-14 g. Its internal organs develop and improve every day, nail beds appear on small fingers, and the rudiments of marigolds appear in them. At this stage, the genital organs of the fetus also appear, but it is still not possible to determine the sex of the unborn child. Future mom all the time listens to the sensations: the first fetal movements are a real event for the whole family! As soon as the baby grows up and gains weight, they will become really noticeable.

13 weeks pregnant

The 13th week of pregnancy is one of the most favorable periods for the expectant mother and baby. During this period, the threat of miscarriage is significantly reduced, the fetus is safer and subject to fewer risks than at the beginning of pregnancy. The expectant mother can breathe a sigh of relief, but she should not relax completely either: the end of the first trimester still requires careful attention to her health. Proper nutrition for a pregnant woman, compliance with all the prescriptions of the attending physician, walks in the fresh air and complete peace of mind are the key to a successful pregnancy at this stage.

The end of the first trimester of pregnancy makes significant changes in the body of the expectant mother. At the 13th week of pregnancy, the uterus constantly increases in size, rises higher and higher. Now it fills almost the entire hip area and rises into the abdominal area. At each examination, the gynecologist will now measure the height of the uterine fundus. Normally, the height of the fundus of the uterus corresponds to the obstetric period in weeks and is easily palpable. The approximate size of the uterus of a pregnant woman for a period of 13 weeks is 10 cm wide and 13 cm high. It becomes more elastic and softer,

The tone of the uterus in the second trimester will no longer be so terrible, as it becomes more elastic and softer, and the contractions are short. If a pregnant woman feels slight pulling pains in the lower abdomen, it is necessary to exclude any physical exercise and lay down. More severe pain, accompanied by weakness, fever, specific vaginal discharge, is a serious reason to consult your doctor. Be carefull!

14 weeks pregnant

The 14th week of pregnancy is the beginning of the second trimester, it can be called the calmest period in the process of bearing a child. Irritability and nervousness are replaced by a feeling of peace and tranquility, but increased tearfulness can accompany you throughout the entire period of pregnancy. Enjoy your position, good health and mood.

The abdomen at the 14th week of pregnancy increases in size, the expectant mother gains about 2-3 kg by this time, this occurs with an increase in the volume of blood and lymphatic fluid, and with an active growth of subcutaneous fat. Since the hormonal background has changed, you should not abuse sweet foods and pastries during this period of pregnancy - they can lead to a sharp weight gain.

At the 14th week of pregnancy, neoplasms may appear on the skin of a woman - moles and papillomas (soft warts). Do not worry, papillomas during pregnancy are a common occurrence. When the hormonal background returns to normal, they will disappear. If you have previously had papillomas, and you notice that they change in size and grow, and birthmarks- increase and darken, it is necessary to consult a doctor to find out the reasons.

Also, the expectant mother may have another trouble - warts (warts) in the vagina or anus. Their appearance is associated with the papillomavirus - this is also a problem with which you should consult a doctor. Warts during pregnancy are especially dangerous, they can cause complications, as they tend to grow, thereby clogging the birth canals, subsequently preventing childbirth. However, the most unpleasant thing is that during childbirth, your baby can also become infected with this virus. So the treatment of genital warts is a mandatory measure to maintain the health of not only the expectant mother, but also the baby.

15 weeks pregnant

The development of pregnancy at week 15 introduces some adverse changes in the body of the expectant mother. During this period, pregnant women notice a deterioration in the condition of the skin, hair and nails, as well as crumbling of the teeth. This is due to the fact that all energy costs and nutrients from the mother's body go to the development of the fetus. The fetus in the second trimester of pregnancy continues to actively develop and grow, it requires large amounts of nutrients, vitamins and trace elements, especially calcium and proteins.

The abdomen at the 15th week of pregnancy, following the fetus, grows and becomes even more rounded. Some pregnant women may notice during this period the appearance of a dark strip on the abdomen from the navel down. Do not worry - this is a temporary phenomenon that will disappear shortly after childbirth.

The uterus at the 15th week of pregnancy becomes even larger compared to the previous 14th week. The height of the bottom of the uterus is 14 cm. The pregnant woman can already feel it on her own by placing her palm on the lower abdomen about 4-5 fingers below the navel. The uterus no longer presses on the bladder, so the frequency of urination returns to normal. But the uterus still presses on the intestines: problems with stools are not excluded.

It is during this period that the expectant mother can feel the first movements of the baby, because he has already reached the size of a small apple! True, sometimes they are even difficult to realize, they are so easy.

The belly at 16 weeks of gestation continues to round,

Allocations at the 16th week of pregnancy can also change their character: they become milky in color and increase in volume. This is completely normal, such discharge is normal.

Due to the increase in the conductivity of nutrients in the vessels of the placenta, the expectant mother may complain of a rapid heartbeat. In pregnant women at week 17, bleeding gums and nosebleeds may occur as a result of such heart activity. Women also note increased sweating and more abundant vaginal discharge during this period.

However, it is better to choose vitamins for pregnant women together with your doctor in order to avoid trouble.

There is a special table - a fetal movement test, in which the expectant mother notes every tenth movement of the child from 9:00 to 21:00. Under normal conditions, the tenth movement is noted until 17:00. If the number of movements within 12 hours is less than 10, tell your doctor.

The kid is sensitive to sharp pops or knocks, they cause him anxiety, and screaming and noise frighten him. The most pleasant sound for the baby, even after birth, is the beat of the mother's heart. He has already developed taste buds, grasping and sucking reflexes are actively developing. He looks less and less like a wrinkled old man, the skin slowly smoothes and changes color.

The start of the third trimester is a time to be vigilant. If you notice watery discharge from the vagina, do not hesitate to visit the doctor: it is possible that amniotic fluid is leaking and there is a risk of giving birth prematurely.

Bloody discharge at the 26th week of pregnancy may indicate placental abruption, but only a doctor can determine this more accurately.

27 weeks pregnant

The development of the child at the 27th week of pregnancy continues to gain momentum: important changes are taking place in his body.

Every day, the movements of the fetus are felt by the expectant mother more and more sharply, she can already recognize even the hiccups in the baby by slight rhythmic shudders inside. This process does not cause any inconvenience to the child and can last several minutes.

At the 27th week of pregnancy, some expectant mothers may experience involuntary urination that occurs during sneezing or strong laughter. This is due to the fact that the uterus at the 27th week of pregnancy puts quite a lot of pressure on the bladder. In order not to be in an awkward situation, use special sanitary pads. Heartburn during pregnancy, nausea and frequent constipation are also the result of uterine pressure on internal organs. Try to eat in small portions, but often, do not abuse sweet and starchy foods. Compliance with the drinking regime, feasible physical activity, exercises for pregnant women - all this will also help you cope with ailments.

The third trimester is a time of special control. The expectant mother should pay attention to the number of fetal movements, the nature of the discharge (for example, bloody discharge may indicate placental abruption, and watery discharge may indicate the onset of preterm labor) and specific pains. Timely diagnosis by the attending physician will help to avoid trouble and endure the baby before the due date.

The 28th week of pregnancy has come. The child at this stage of development is already quite large and slightly less mobile. It becomes crowded in his mother's tummy, the baby practically does not change the position of the body, but continues to push his mother with his legs and arms. The expectant mother needs to continue to monitor the movements of the fetus and mark them in a special table. At 28 weeks of gestation, the baby opens its eyes for the first time and can distinguish between light and shadows. The child's brain is actively developing and has several clear convolutions.

If you are still working, try not to overwork yourself. Even doing household chores, ask relatives for help. Premature birth at this time is a phenomenon, although not universal, but there is still a risk. Take care of yourself!

The expectant mother during this period should monitor her weight. Weight gain at 29 weeks pregnant should be about 10-12 kg. The rate of weight gain is approximately 300-350 g per week. If a pregnant woman recovers more rapidly, it is necessary to make sure that this is not due to fluid retention in the body. Edema during pregnancy at this time is found in most expectant mothers, a salt-free diet, correction of the drinking regimen and special exercises for pregnant women will help solve the problem.

This is due to the acceleration of metabolism, which causes the activation of sweating processes and increases the load on the heart. In some pregnant women, pressure decreases, a rapid pulse appears.

Only a doctor (with the help of careful palpation) and an unscheduled ultrasound at the 30th week of pregnancy can determine the presentation most accurately.

31 weeks pregnant

The uterus at 31 weeks of gestation continues to increase in size and rise higher, putting more and more pressure on the internal organs. This leads to such unpleasant phenomena as heartburn, constipation or hemorrhoids. During pregnancy for a period of 31 weeks, it is necessary to constantly monitor the condition of the expectant mother, especially if there is uterine fibroids during pregnancy or scars after cesarean section.

The nutrition of a pregnant woman during this period should be as useful and easily digestible as possible. To prevent nausea, heartburn and constipation, you need to eat small meals, but often.

The development of the child at 31 weeks of gestation continues, outwardly, he is already becoming more and more like a newborn baby. The skin of the baby turns pink due to subcutaneous fat, which hides his blood vessels, the capillaries through it no longer shine through. The baby is actively gaining weight, his internal organs and reflexes are developing and improving. Fetal movements at 31 weeks of pregnancy are felt by the mother very well, experts recommend continuing to monitor the baby's activity and filling out a special table of fetal movements.

32 weeks pregnant

Started 32 weeks pregnant. The estimated due date is getting closer, the expectant mother is increasingly worried about the health of her unborn child. At the 32nd week of pregnancy, the stomach begins to cause a lot of inconvenience. Pain in the lower back and legs, the inability to take a comfortable position for sleeping, some clumsiness - it is not at all surprising that at this time most women feel tired, they want to end the pregnancy and meet the baby as soon as possible.

At the 32nd week of pregnancy, the uterus continues to put pressure on the internal organs, causing shortness of breath, heartburn and frequent constipation. A pregnant woman has training contractions - almost painless contractions of the uterus, preparing her for the upcoming birth. Some women report that at 32 weeks pregnant they sweat more than usual and feel hot in the body. This is due to the acceleration of metabolic processes in the body of a pregnant woman, which affect the work of the heart and the process of sweating.

The fetus at 32 weeks of gestation continues to grow and gain weight. It is already the size of a large head of Beijing cabbage and weighs about 1.6-1.7 kg. The baby hears how the mother's organs work, listens to her voice and is able to distinguish its sound from any other. Outwardly, the baby is also changing - hair, nails grow, wrinkles are smoothed out, cheeks appear, the original lubricant is gradually washed off. Almost all the organs of the child are already formed, the head and torso are proportional, it remains to add weight. Another important achievement of this period is the laying of the baby's own immunity. Ultrasound will help to fully assess the development of the child at this stage. At the 32nd week of pregnancy, the doctor will determine the presentation of the fetus, as well as assess the condition of the placenta, umbilical cord and the amount of amniotic fluid.

Throughout pregnancy, the expectant mother should beware of viral and infectious diseases, since any disease and methods of its treatment will certainly affect the health of the baby. colds on later dates pregnancies are dangerous because they accelerate the aging process of the placenta, and this, in turn, threatens the development of fetal hypoxia and disruption of the delivery of nutrients from mother to child.

33 weeks pregnant

The 33rd week of pregnancy has come. The child has reached the size of a pineapple and already weighs about 2 kg. Every day he is getting tighter in his mother's stomach: no somersaults, no coups. The amount of amniotic fluid also decreases, the movements of the fetus are felt by the mother more and more acutely. At this time, the development of the child continues to gain momentum: the immune, nervous and endocrine systems complete their formation, muscle mass and subcutaneous fat continue to grow. If suddenly the expectant mother begins premature birth at 33 weeks of gestation, the chance of having a live and healthy baby is very high.

At the 33rd week of pregnancy, the belly of the expectant mother continues to grow, causing more and more discomfort while sleeping, walking or doing business. The uterus at 33 weeks pregnant rises even higher and puts even more pressure on the stomach and other organs. The pregnant woman still experiences heartburn, sometimes there is a burp. Breathing becomes difficult and shortness of breath appears after exercise. After a couple of weeks, the pregnant woman's belly will begin to sink down and the woman will feel a little better.

Edema during pregnancy at this time is a ubiquitous phenomenon. Expectant mothers complain of swelling of the legs (especially in the ankle area), which increases after exercise or walking. Edema of the legs in pregnant women is associated with a violation of the speed of blood flow: after all, the growing uterus puts pressure not only on the internal organs, but also on the blood vessels. And the blood, being under pressure, retains water in the legs.

To prevent swelling during rest, you need to put your feet above your head, for example, on a pillow or a rolled up blanket, wear comfortable shoes for pregnant women and do special exercises. A pregnant woman is not recommended to stand, sit, stay in stuffy rooms for a long time. The nutrition of a pregnant woman should be balanced and healthy. To prevent swelling, it is necessary to limit or completely eliminate the use of salt, salty foods and spicy foods. Salt tends to retain fluid in the body, and generously spiced dishes can cause not only an attack of heartburn, but also intense thirst.

34 weeks pregnant

Started 34 weeks pregnant. What happens during this period? The body of the expectant mother begins to intensively prepare for the upcoming birth. For example, a large amount of hormones are released into the bloodstream, which increase the elasticity of certain joints and ligaments - all this is necessary for easier progression of the child through the birth canal. The enlarging uterus at the 34th week of pregnancy puts a lot of pressure on the bladder, for this reason, the expectant mother has more frequent urination, sometimes urinary incontinence may occur.

Pregnant women continue to experience heartburn, some mothers complain of difficulty breathing, problems with stools and hemorrhoids. Edema during pregnancy (especially severe) is a reason to see a doctor and pass all the necessary tests. Preeclampsia of pregnant women is a serious pathology in which toxins are released into the body of the expectant mother, which can lead to impaired fetal development at 34 weeks of gestation and even death. The presence of protein in the urine and a change in blood pressure indicate the development of preeclampsia in a pregnant woman.

The baby at 34 weeks of gestation continues to grow actively. It has already reached the size of a nutmeg gourd and weighs approximately 1.9-2 kg. In the third trimester, actively formed the cardiovascular system child. The frequency of his heartbeat is almost 2 times higher than that of an adult. Putting your ear to the belly of the expectant mother, you can hear the fetal heartbeat. From the 34th week of pregnancy, the baby gains the necessary weight, the primary hair growth decreases and, along with it, the original lubricant. The baby's skin becomes paler and smoother, the work of the kidneys and all vital systems is getting better. If a mother-to-be goes into premature labor at 34 weeks pregnant, there is a huge chance that the baby will survive and be born healthy (albeit small).

35 weeks pregnant

So, you are gradually approaching the estimated date of birth, the 35th week of pregnancy has come. It becomes more and more difficult to do the usual things and maintain the former activity. At the 35th week of pregnancy, the breasts of the expectant mother are already preparing to feed the baby with might and main: it has increased in size, filled up and aches. Nursing bra is what you need. It will not squeeze and irritate, and will support your enlarged breasts well.

The belly has already become quite large and causes a lot of inconvenience. The uterus at the 35th week of pregnancy became huge, crushed the stomach and lungs. At the end of the 35th week, the pregnant woman's belly will begin to sink and it will become easier to breathe. If it has become very difficult for the expectant mother to breathe, it is necessary to perform a special exercise for pregnant women, which will help reduce pressure on the internal organs: get on all fours and inhale and exhale smoothly. In this position, you can stand from 5 minutes to half an hour, several times a day.

The baby at 35 weeks of gestation continues to grow and has already reached the size of a nutmeg. Its weight increases every week by 200-250 g. The movements of the fetus become more constrained, because there is practically no free space in the mother's stomach. Now he is not so much pushing as rolling, sticking out different parts of his body. At this stage, the intrauterine development of the fetus is already quite high, the work of its internal organs and reflexes has been established. If a mother-to-be goes into premature labor at 35 weeks of gestation, the chances of having a healthy baby are very high. However, experts agree that in order to guarantee the survival of the child and its further development, pregnancy must be maintained until the expected date of birth.

36 weeks pregnant

36 weeks of pregnancy is the final stage of the entire period of bearing a child, according to gynecologists. The expectant mother at this stage of pregnancy will probably have to visit her doctor until the onset of childbirth. He will carefully monitor her blood pressure and protein content in her urine to rule out the risk of developing such a serious pathology as preeclampsia. It may be necessary to perform an ultrasound at 36 weeks of gestation to detect fetal presentation, check the condition of the placenta, amniotic membranes, exclude the risk of cord entanglement and assess the amount of amniotic fluid.

It is time for the expectant mother to start solving organizational issues: choose the place of delivery, choose a doctor and pack a bag for the hospital. Starting from the 36th week of pregnancy, childbirth can occur at any time, and the expectant mother must be ready for this. Since the obstetrician cannot determine the onset of pregnancy with an accuracy of up to a week, an error of 2 weeks is not uncommon, and at a period of 37-38 weeks of pregnancy, childbirth is no longer considered premature.

At the 36th week of pregnancy, the belly of the expectant mother gives a lot of inconvenience due to its large sizes. Due to the load, the woman feels pain in the lower back and legs, suffers from swelling and moves more difficult. The uterus at the 36th week of pregnancy continues to put pressure on the internal organs, causing shortness of breath and heartburn. In some women, a prolapse of the abdomen occurs at this time: the baby is slowly moving closer to the “exit”, occupying the pelvic floor with the presenting part (head or buttocks). By the way, a baby at 36 weeks of gestation is already the size of a large papaya, its weight is approximately 2.5 kg.

Almost all women experience fear of childbirth, especially if they are for the first time. At 36 weeks, expectant mothers become increasingly irritable, anxious and nervous. Good helpers in the fight against fear will be meditation, relaxation, yoga for pregnant women, relaxing massage, listening to music, reading books, communicating with loved ones or a personal psychologist.

37 weeks pregnant

At 37 weeks of gestation, the baby is already ready for birth, but his body continues to change and prepare for childbirth. The baby's body gradually becomes plump due to the accumulating subcutaneous fat, the skin smoothes, becomes elastic and acquires pink shade. The fetus at the 37th week of pregnancy is fully developed: all the systems of its body are ready to start working, the hormone cortisol is produced, which contributes to the maturation of the lungs. Meconium has accumulated in the baby's intestines - the original feces, which will come out on the first day, from 3 to 20 hours after birth. By the way, the removal of meconium from the intestines of the newborn will be facilitated by colostrum secreted from the mother's breast in the first time after childbirth.

By the 37th week of pregnancy, the uterus has reached its maximum size: it weighs about a kilogram, its volume is 4-5 liters. The pressure on the bladder increases, the pregnant woman has back pain, and shooting pain in the legs and perineum is also possible. The stomach at the 37th week of pregnancy hardens several times a day - training contractions occur. At this time, aging of the placenta is noted, harbingers of close births may appear: exit of the mucous plug (yellowish discharge with streaks), lowering of the abdomen (the child occupies the position of the presenting area in the small pelvis), slight liquefaction of the stool.

At 37 weeks, the baby's movement often brings pain expectant mother, now his stomach is very crowded: the amniotic fluid has become even smaller, the size and weight of the child are increasing. It turns out that the uterus at the 37th week of pregnancy now puts pressure not only on the internal organs of the mother, but also pinches the baby. Fetal movements must be controlled at the 37th week of pregnancy: there should be at least 10 per day. In the last days of pregnancy, the activity of the child decreases, he calms down a bit and prepares for his birth.

38 weeks pregnant

The 38th week of pregnancy has come - an alarming waiting period for the expectant mother. At this time, the pregnant woman should be prepared for the fact that she can be taken to the hospital at any time. If you haven't packed your bag for the hospital yet, now is the time to take care of it. Also collect all Required documents: you need to take your passport, medical policy, exchange card and birth certificate to the maternity hospital. Put all the documents in one folder or file and carry it with you in your purse, especially when traveling.

The belly at 38 weeks of gestation can be truly huge: the baby has taken all the free space and continues to gain weight. It is getting harder and harder for him to move, as the uterus at the 38th week of pregnancy squeezes the body from all sides. At this stage, important improvements take place in the body of a little man, the fluff disappears partially or completely - lanugo and original lubricant covering the baby's skin, facial features become more and more refined. At 38 weeks of gestation, the baby takes its place in the mother's pelvis and is preparing to be born with might and main.

During this period, expectant mothers may feel the harbingers of childbirth: training contractions, pain in the hip area and sacrum, pulling pains in the lower abdomen, reminiscent of menstruation. Mucous discharge from the vagina at 38 weeks of gestation may also indicate an impending birth.

Expectant mothers often worry: how to identify contractions and distinguish them from false ones? Experts recommend staying calm, because you definitely won’t miss childbirth. Real contractions are more tangible and painful than training ones, they are repeated periodically, increasing their frequency and intensity incrementally. To distinguish false contractions from real ones, change your position: stand up, walk around the room, lie down. If the contractions have stopped - do not worry, most likely they are false.

39 weeks pregnant

The 39th week of pregnancy has come, the baby is already fully formed and ready to be born at any moment. The baby has reached the size of a small watermelon and weighs about 3.2 kg. His lungs are developed enough to finally take his first breath. The movements of the child are becoming less and less active due to the cramped mother's womb, the expectant mother should not stop watching the activity of her child and, in case of a "calm", immediately consult a doctor.

At week 39, pregnant women begin active "nesting" - a condition in which a woman strives with all her might to clean up the mess and create as much comfort as possible in the house. At this time, women can feel a surge of strength, an unusual lightness (despite a huge belly at 39 weeks of pregnancy) and a desire to “turn mountains”. But do not be too zealous: such intense physical activity may well provoke childbirth at 39 weeks. Entrust the cleaning and home improvement to the future dad or caring relatives.

For a successful delivery and well-being of the expectant mother and child, doctors recommend not to neglect long walks. Ideally, in late pregnancy, you need to walk at least 3 hours a day, if there are no problems and bed rest is not indicated for you. Fetal hypoxia is a dangerous phenomenon throughout pregnancy, the end of the third trimester is no exception. For its prevention, it is important not only to breathe fresh air, but also continue to eat right, perform feasible exercises for pregnant women, avoid stress and any conditions that negatively affect you and your pregnancy.

At 39 weeks pregnant, many women lose up to 2 kg in weight. There is nothing to worry about - the body removes excess fluid. At the 39th week of pregnancy, the total increase in women averages from 10 to 15 kg, but it can be either more or less. It depends on the characteristics of the body of the expectant mother and is one of the harbingers early delivery.

40 weeks pregnant

The 40th week of pregnancy is the final stage of bearing a child, and the body of the expectant mother is almost ready for the upcoming birth. Now you should have everything ready for the birth of your baby - from the bag to the hospital and documents, to the complete order in the apartment and the availability of everything necessary to care for your baby. Fear of childbirth, increasing tension, anxiety - all this negatively affects your baby. Try to set yourself up positively, because very soon you will be able to see and pick up your long-awaited son or daughter!

At this time, the expectant mother should continue to count the movements of the fetus: there should be at least ten of them during the day. If suddenly a child at 40 weeks of gestation suddenly calms down or is too active, consult a doctor: he may be experiencing oxygen starvation or other problems that require the immediate intervention of specialists.

One of the most important signs of imminent labor is the discharge of the mucous plug. A plug is a clot of mucus that closes the cervical canal during pregnancy and protects the fetus from infections that can enter the uterus from the vagina. The hormone progesterone, which is responsible for carrying a fetus, ceases to be produced at 40 weeks of gestation. The cervix becomes softer, the canal begins to open, and after that the mucus plug comes out. Other equally indicative harbingers of childbirth are lowering of the abdomen, the occurrence of training contractions, pain in the lower back, sacrum or womb, and the outflow of amniotic fluid. Be alert!

If you're 40 weeks pregnant and labor isn't starting, don't worry, your "X" hour is coming soon!

41 weeks pregnant

The expected due date is past, and your pregnancy is still ongoing and, by the way, is not considered post-term. At this time, the expectant mother feels clumsy and clumsy, gets very tired and increasingly suffers from sleep disorders. The reason is very big belly at 41 weeks pregnant, making it difficult to take at least some comfortable position. Most women complain of severe irritability and nervousness that seem to arise out of nowhere. This is directly related to their hormonal background and the excitement that expectant mothers experience while waiting for childbirth. If you are afraid of childbirth, discuss this with your doctor, as well as with your family or personal psychologist: now more than ever you need special support and understanding.

At 41 weeks pregnant, the discharge in a pregnant woman may become more intense and look like mucus (clear in color or colored pinkish, yellowish or creamy). Such discharge indicates the discharge of the mucous plug from the cervix and the possible approach of the onset of labor.

Just before childbirth, a pregnant woman may lose amniotic fluid, which looks like a clear, odorless, thin liquid. The discharge of water in pregnant women can occur in different ways: it can be a leak, a trickle, or a one-time outpouring. Many future mothers may not notice this process at all. This happens in cases where a small crack or a small gap occurs on the fetal bladder - then the water simply leaks. If the expectant mother uses sanitary pads, she may confuse them with vaginal discharge.

Sometimes pregnant women try to induce labor themselves by taking castor oil or other dubious or even dangerous methods to speed up labor. Experts urge women "not to engage in amateur activities" and seek timely help.

42 weeks pregnant

Many women who carry a baby up to 42 weeks often become nervous because labor does not begin. Don't worry, you have a few days left to give birth. Perhaps you are already observing some of the harbingers of childbirth and are mentally preparing for a trip to the hospital.

At 42 weeks of gestation, there is a risk of placental aging and the development of various pathologies. Fetal hypoxia, deficiency of nutrients, the likelihood of infection or cord entanglement - all this can be prevented if you contact your doctor in time and undergo an examination. The doctor will listen to the fetal heartbeat, check the condition of the cervix, placenta, membranes, umbilical cord, and measure the abdomen. At the 42nd week of pregnancy, the expectant mother may be prescribed additional examinations and, if necessary, will be admitted to a hospital for observation.

If you want to give birth on your own, 42 weeks is the last week for such an opportunity. When there are no contractions, doctors decide to induce labor. Be prepared for the fact that a large child is more difficult to go through the birth canal and, as a rule, the postpartum recovery period will be longer. Also, if the fetus has an ossification of the skull, during natural childbirth, a woman may have tears. To avoid serious damage to the genitals and perineum of a woman, as well as traumatic brain injuries in a baby, doctors may resort to surgical dissection - an episiotomy.

Description

This calculator will allow you to calculate what stage of pregnancy you are currently in, the date of future birth, the date of conception, and even the zodiac sign of the future baby and his zodiac animal according to Eastern calendar. You can also determine the age of the fetus, its weight and height, and how much time is left before delivery. To do this, you need to enter the date of the first day of your last period and the length of your menstrual cycle. In addition, our calculator generates a very convenient and practical weekly pregnancy table. Using it, you can navigate which week of pregnancy you are currently in, as well as track the height and weight of your unborn child.

The need to calculate the gestational age by weeks occurs in almost every pregnant woman and more than once during pregnancy. And this is necessary not only in order to simply know your due date or correctly track the pregnancy calendar. I also want to calculate the duration of pregnancy and childbirth in order not to doubt the correctness of the doctor’s actions, if they make a mistake in the consultation - this can also affect the date of going on maternity leave, you don’t want to work an extra couple of weeks, right?

First, some general information.

Our calculator will help you calculate the obstetric gestational age, it is slightly different from the actual life of the fetus. Gynecologists build all their calculations on the date of the first day of the last menstruation, and do not count from fertilization, this is due to the ease of error in the date of conception.

Ovulation in a woman can significantly shift in time, especially if she does not have a regular cycle, and of course, not everyone can know the exact date of fertilization, it is difficult to calculate the gestational age by ovulation. And the date of the beginning of the last menstruation, as a rule, is known.

We have a special calculator that allows you to independently calculate the gestational age online. He will give you information not only about the obstetric gestational age, but also the date of conception, the age of the fetus, the date of birth.

The problem may arise if yours is not regular. How to correctly calculate the gestational age by menstruation with an irregular cycle? You need to add the length of the last 6 cycles and divide by 6, so you get average duration, this is the number of days and must be entered in the calculator field.

All data obtained can be easily controlled using other calculation systems.

You can accurately calculate the gestational age (well, or relatively accurately, as gynecologists think) using the Negele formula. It does not take into account the length of your cycle and therefore the result may differ from the period that our calculator gives, but this will certainly coincide with the calculations of the gynecologist: we subtract 3 months from the first day of the delay in menstruation and add 7 days to the date obtained. This is your due date. Calculate the gestational age by months, weeks and days, as with our calculator, using this formula will not work.

If you had an ultrasound, the doctor measured the development of the baby. Its weight, the length of the bones make it possible to calculate the gestational age by ultrasound, but this calculation is accurate only in the first trimester, the longer the period, the greater the difference in physical development in different children, and there is a higher risk of error in determining the timing of pregnancy.

Almost all calculation methods carry a certain risk of error, which is why only 4% of children are born on the PDR (preliminary date of birth).

It is better to evaluate the results of calculations in a complex (ultrasound, date of the last menstruation, first movement and other dates and signs). And still, the date of birth can fall between 37 and 42 weeks of pregnancy.
