As soon as a woman becomes pregnant, she is immediately interested in the question: how to independently determine the duration of pregnancy at home? Indeed, with the help of such calculations one can calculate approximate date the birth of your child. Besides future mom may not know the exact day of conception.

Some try to calculate the onset of pregnancy based on the timing of ovulation, but you should know that ovulation occurs between the 8th and 16th day of the cycle. Therefore, fertilization can occur between the 8th and 18th day of the menstrual cycle, taking into account the viability of sperm in the woman’s genital tract. After all, it is in this case that conception most often occurs. In addition, the duration of pregnancy may not be 40 weeks, since normal pregnancy is full-term by 37-38 weeks, so after this period, labor can begin at any time.

A pregnant woman may also have more than one fetus, so childbirth can occur 2-3 weeks earlier than with one fetal pregnancy. Also, birth can be affected by any individual characteristics women, these may be diseases, for example, diabetes, hypertension or other diseases. But, despite this, it is still possible to determine the approximate gestational age at home.

Determination of gestational age, relative to ovulation and date of conception

Determine correctly exact date pregnancy, you can use a calendar. As you know, ovulation is the period of the menstrual cycle in which the conception of a child occurs. And during ovulation, an already mature egg is released from the female ovary into the fallopian tube, which is met by a sperm. As a result, pregnancy occurs. The date of ovulation is used to determine the duration of pregnancy. There are small tips on how to recognize the symptoms of pregnancy in a woman.


A woman ovulates approximately in the middle of the menstrual cycle. And if a woman’s cycle is about 28 days, then ovulation will occur around day 14. And when a woman’s menstrual cycle is 35 days, ovulation will occur on the 17-18th day of the menstrual cycle. Therefore, the exact period of pregnancy should be counted from the day of ovulation. Moreover, knowing the day of ovulation, you can plan your pregnancy and know the month and approximate date when the baby is born.

It is worth noting that you can easily determine your ovulation yourself at home using ovulation tests that are sold in pharmacies, or you can determine it by measuring your basal temperature. To do this, you will need to cleanse the intestines at home using an enema, and then measure the temperature in the rectum with a thermometer. Peculiarities:

  1. Throughout the first half of the menstrual cycle, the basal temperature remains at 37 degrees.
  2. The day before ovulation it decreases slightly.
  3. On the day of ovulation and all subsequent days, the temperature will rise and will be 37-37.2 degrees.

Therefore, how to accurately determine how far I am in pregnancy by the date of ovulation can be done using a regular thermometer.

However, there are also women who know how to determine the duration of pregnancy, focusing on their subjective feelings. And these sensations include pain in the lower abdomen, an increase in the amount of vaginal discharge, or an increase in libido. In addition, in some cases, a woman may experience no pain during menstruation, which indicates some positive changes.

Therefore, it is not difficult for such sensitive women to determine the time when conception occurred. But still the most in an exact way Ultrasound is used to determine the duration of pregnancy. In addition, with the help of this study you can find out the date of ovulation. However, constant trips to the ultrasound room will require a lot of money, so you can try more affordable methods for calculating the gestational age.

Determination of gestational age relative to the date of the last menstrual period

This is perhaps the simplest and known method determination of pregnancy juices and it is called the Naegele method. However, this method helps to calculate the due date rather than the pregnancy. By this method to determine the due date it will be required from the first day last menstrual period you should subtract three months, and then add seven days to the number. And in accordance with the obtained date of birth, you can easily calculate the duration of your pregnancy.

Determination of pregnancy due to an experienced gynecological examination

Without a doubt, if a woman came for an examination to a gynecologist in the very first weeks of pregnancy, for example 3-4 weeks, then it will not be difficult for him to determine the duration of pregnancy. And in this case, the specialist determines the gestational age based on the size of the uterus.

It will not be difficult even in a period when a woman has just recently taken a pregnancy test and immediately came to the gynecologist.

For example, at 4 weeks its size can be compared chicken egg, and at 8 weeks the size of the uterus can be compared to a goose egg. And if this is a very experienced gynecologist, then the obstetric examination will be professional; as a result, he can determine the duration of pregnancy using a vaginal examination and set the date with an accuracy of one day.

After a period of 8-12 weeks, it is very difficult for a gynecologist to determine the size of the uterus, since each woman’s uterus and its size may differ. Therefore, the gynecologist can not only determine a more accurate period, but also provide full instructions on what is possible for pregnant women. For example, is swimming beneficial for pregnant women or not, or what exercises or exercises should be done to correct posture and strengthen muscle tone. During this period experienced doctor you can determine the gender of the unborn child or several at once.
Determining the gestational age using the result of a modern ultrasound examination It may be more likely to determine the exact period if an ultrasound is performed in the early stages, this is 8-12 weeks. For more long term Each child develops differently, so it will be difficult to determine an exact date. And if the fetus gains insufficient weight after 20 weeks of pregnancy, then at this examination a diagnosis of poor fetal development is made.

Typically this diagnosis is given to women of fragile build. And on the one hand, this is wrong, because a full-term baby can weigh 2.8 kg or 4 kg. Therefore, the weight and size of each child may vary significantly. For this reason, it is not necessary to pay attention to the period indicated on ultrasound in the 2-3 trimester of pregnancy.

Every expectant mother is interested in the question of how to accurately determine the duration of pregnancy? After all, it is otherwise impossible to understand when the long-awaited meeting with the baby will take place, when should a woman go on maternity leave, when should she register with an antenatal clinic?

Before answering you how to determine pregnancy in the early stages, it is worth noting that there is an obstetric and true pregnancy period, let's see how they differ.

Obstetric and true method for determining pregnancy and due date

If a woman suspects that she is pregnant, then after the examination the doctor will ask about the date of her last menstruation: based on this, the gestational age will be calculated. When a woman begins her period, the egg matures. In fact, it is after fertilization that we can consider that pregnancy has occurred, but doctors calculate the period differently. The average duration of pregnancy is 280 days, that is, 40 weeks or 10 months from the start of the last menstruation. It turns out interesting: conception has not yet occurred, but obstetricians are already beginning to count the gestational age.

As for the true period, it is counted from the day of ovulation (conception), on average it is 2 weeks behind what is announced by obstetricians. The date of birth is also calculated, but the above formula (280 days from the date of the last menstruation) is very inaccurate: the characteristics of the expectant mother’s body can make significant adjustments. On average, pregnancy can last from 38 to 42 weeks, so no one can tell you the exact day the baby will appear.

If the date of conception (ovulation) is known, the gestational age can be determined quite accurately.

Basically, ovulation occurs on the 14th day after the onset of menstruation - during this period the probability of pregnancy is maximum. But this rule only applies to women with a normal cycle (28 days): if the cycle is shorter (22-24 days), then ovulation occurs on days 10-12, and if the cycle is long (33-35 days), then you need to wait for ovulation on days 16-19. the main problem the fact is that in the first days, and for some women even weeks of pregnancy, it is almost imperceptible: some expectant mothers even have their periods on schedule, so it is very difficult to independently determine the due date. How to determine the exact date of pregnancy?

Methods for determining the timing of pregnancy

Ovulation date . Even though ovulation may occur in each month different days, you can calculate the date of conception. To do this, many women use special tests and measure basal temperature. Many representatives of the fair sex can understand that ovulation has occurred by how they feel: a change in the nature of discharge, pain in the lower abdomen, increased libido. It is important to consider that determining the gestational age by the day on which sexual intercourse took place is not reliable. Spermatozoa that enter the fallopian tubes and the uterus, retain their ability to fertilize for up to 7 days, waiting for the egg to release from the follicle. Therefore, it is better to keep a schedule of monitoring ovulation, because the egg that comes out of the ovary can only exist for a day. So, if you are planning to conceive, remember this fact.

Menstrual cycle . Actually, this is the method that obstetricians use. It is enough to remember the last date of menstruation: the number of weeks that have passed since that time corresponds to the obstetric period of pregnancy. But this method cannot be considered reliable, especially if a woman’s cycle is irregular.

Examination by a doctor, measurement of the uterine fundus . Often, from the 8th week, the gynecologist can accurately determine the gestational age based on the size of the uterus.

  • At 4 weeks the uterus is the size of a chicken egg, at 8 weeks it is the size of a goose egg.
  • At the 3rd month, the uterus already reaches the size of a newborn’s head, asymmetrical lines are smoothed out, and it fills the entire upper part of the pelvic cavity.
  • Already from the 4th month, the doctor will be able to palpate the fundus of the uterus, and the height of the fundus is used to indicate the gestational age. But this indicator can be influenced by a number of factors: multiple births, a large number of amniotic fluid, malpresentation fruit and much more.
  • At 16 weeks, the fundus of the uterus is located midway between the navel and pubic bone.
  • At the end of the 5th month, the abdominal wall is already noticeably protruding, and the fundus of the uterus is 2 fingers lower than the navel.
  • At the 6th month (24 weeks), the fundus of the uterus already reaches the level of the navel.
  • At 28 weeks it is located 2-3 fingers higher than the navel.
  • At 32 weeks (8th obstetric month), the fundus of the uterus is located in the center between the xiphoid process of the sternum and the navel, the navel is flattened.
  • At 38 weeks (9th obstetric month), the fundus of the uterus rises to the costal arches and the xiphoid process, this is the highest point of the fundus.
  • At 40 weeks, the fundus of the uterus drops and the navel protrudes.

Ultrasound examination . How can you accurately determine your gestational age? - of course, with the help modern technologies. Using an ultrasound, you can accurately find out the gestational age: it is advisable to do this before 12 weeks - in the future, there may be errors, since the development of each baby is individual: some babies are larger, others are miniature. Based on the results of the ultrasound, you can be told both the true age of the fetus and the obstetric period.

First movements . This method is not suitable for those mothers who do not know how to determine pregnancy in the early stages, because first-time mothers feel movements at 19-20 weeks. If this is not the first pregnancy, then expectant mothers may feel the first tremors of the baby a little earlier - at 16-18 weeks, but there is a high probability of confusing them with the “work” of the intestines.

Measuring the length of the uterus . This method is also used by gynecologists: the doctor will measure measuring tape length of the uterus. The length of the uterus in centimeters will be equal to the gestational age: for example, if it is 22 centimeters, then this is the 22nd week of pregnancy. But it is very important that before taking measurements the woman has an empty bladder, otherwise there may be errors.

These are the main methods for calculating gestational age. Install the exact date Pregnancy and childbirth are very rare: your baby will be born only when he is ready for it, and all our calculations are only approximate. Take care of yourself and your baby!

Gestational age- one of the main components that a gynecologist needs to know about for correct management pregnancy. After all, on the basis of this, the doctor will prescribe necessary examinations, tests, routine ultrasound, keep an eye on intrauterine growth and fetal development, will reveal during possible violations. In addition, determining the due date allows you to quite accurately calculate the date of birth and the date maternity leave. It is necessary for the woman herself to know the duration of her pregnancy in order to mentally prepare for childbirth, have time to prepare a room or corner for the unborn baby, and purchase everything for him necessary supplies and clothes.

In this article we will look at how to determine the duration of pregnancy.

Calculate by monthly

For a woman who comes to register at the antenatal clinic, the gynecologist first of all asks a question about when her last period began. It is from this date that he begins to keep a record, despite the fact that fertilization has not yet occurred at this time. It is known that 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 period:

How to determine by date of conception

It is known that conception occurs only during ovulation within 24 hours after the egg leaves the follicle. And the viability of sperm 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 addition, many people at this time have characteristic features: aching pain in the lower abdomen, breast swelling, irritability, copious discharge from the vagina, 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.

(calculation will take a few seconds)

How to calculate using ultrasound

It is possible to find out the gestational age using 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 at this time it is no longer possible to accurately determine the period, since the development of the fetus occurs individually in each woman. It is possible to find out the age of the fetus by ultrasound with an accuracy of one day only in the first weeks after conception.

Determination during examination by a gynecologist

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

Find out the due date by the first fetal movement

In the first pregnancy, a woman begins to feel fetal movements at 20 weeks, in the second - at 18 weeks. But this method does not always allow one to determine the period, since some expectant mothers may feel the first movements of the fetus earlier or later than the indicated weeks - some, due to the structural features of the body, cannot feel the movements of the fetus, others confuse the work of the intestines (increased gas formation) 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 female body after 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 pregnancies, the level of the hormone in the blood increases in proportion to the number of fetuses.

Week of pregnancy HCG level, honey/ml
1 - 2 25 - 156
2 - 3 101 - 4870

Pregnancy manifests itself with special signs in the first days after conception:

  • nausea;
  • irritability.

How to identify them is described below. Having identified similar symptoms, this will not absolutely mean that conception has occurred. Often a girl invents many signs for herself. The methods described below will help pacify curiosity and impatience and determine pregnancy before your period is missed.

But there is a chance that these home research methods will show the wrong answer. It is recommended to use each of them almost immediately after conception.

Processes of transformation and change female body start from the moment the sperm penetrates the egg.

Next comes the attachment of the fetus to the uterus. Then the folk and traditional ways will show the result. If none of the methods gives a positive answer, a woman should not despair. As you know, every organism is unique. Exiting pipes and securing ovum passes in a couple of days, for others this process can take a week. Don’t rush to get upset, but try again a little later.

How many days after conception is it possible to determine?

Carrying a child under your heart is a magical period in the life of any girl, full of discoveries. Many are eagerly awaiting the moment when they will be able to realize their main purpose on earth. And, of course, the girl begins to study all the ways to check pregnancy in the early stages at home.

Naturally, modern pharmacy tests show a plus sign with almost one hundred percent accuracy. They respond to hCG, which constantly rises to three months pregnancy. In the first days after conception, this hormone allows you to determine pregnancy.

The reagent present in the tests starts working at a fairly high hCG indicator, corresponding to 3–4 weeks of pregnancy. Earlier result may not appear.

A few days after conception, they try to determine pregnancy. The day of ovulation should be determined: it is calculated independently, or using a special test. If 2 bright stripes appear, which means that ovulation will occur in a day or two. This is the most suitable day for conception. As a rule, during this period women have abundant transparent discharge, side ache, sometimes even nausea.

It is generally accepted that moment X occurs 5–7 days after the last menstruation. Again, each organism is unique. Fertilization can occur on time, immediately after menstruation.

At home, it is quite easy to determine pregnancy before conception. Every woman should study and know her body and be able to read the signal. After all, many signs allow her to understand what is happening in her body at the moment.

Now let's look at ovulation. On this day, conception supposedly occurred. And a woman needs to be patient. After all, as written above, the consolidation of the fertilized egg occurs in different ways. As soon as this process is completed, hCG rises. It is this hormone that launches new processes and begins to prepare the body for the upcoming, difficult, nine months. Armed with knowledge and scientific facts

, the girl already understands how many days after conception or poorly protected sexual intercourse she should try to determine pregnancy. The common people have invented quite a few methods that answer an exciting question faster than a store-bought test. How to try to determine pregnancy, starting from the first week after conception, is described below.

First signs of pregnancy

  • It is possible to check pregnancy early in the following ways:
  • enlarged belly;
  • by discharge;

with the addition of iodine or soda to the urine.

Of course, the belly takes on a “pregnant” shape later. Yet future mommy notices that his jeans don't fasten. And here a problem arises, how to determine pregnancy by the stomach before a delay in the early stages, if it is not visible at all. This starts processes that accompany a woman throughout her pregnancy.

During the first 4–6 weeks, the uterus changes slightly and is completely unnoticeable. Its parameters are comparable to a chicken egg at the end of the first month. During gestation, blood flow throughout the body and the uterine area especially increases. The walls of the stomach become filled with blood, resulting in slight swelling of the mucous membrane. These processes lead to increased gas formation, constipation. Accordingly, the volume of the abdomen increases.

Many women will perceive these symptoms as indigestion, something that was eaten for dinner. But when the discomfort continues for more than one day, then it is worth considering whether pregnancy is possible.

By basal temperature

Before a missed period, pregnancy is determined by another scientifically based method. It is based on measuring basal temperature several days in a row before menstruation. Two to three days before menstruation, body degrees are slightly higher than normal, the indicator is overestimated by an average of one degree, this is due to a rush of blood and the release of an egg from the body.

You need to prepare in advance and find out all the nuances of how to determine pregnancy before the delay. basal temperature. It won't take a single day.

  1. You should put a thermometer on the bedside table.
  2. Every morning, making minimal movements, the temperature is set.
  3. Basal is measured rectally (the most accurate data) or orally.
  4. Every day you need to write it down.
  5. It is necessary to measure after a delay.

If the temperature is the same, higher than usual, and menstruation does not occur, then the woman will soon become a mother!

By discharge

The following method for determining pregnancy in the early stages will bring the girl closer to the exact answer. The fertilized egg clings to the walls of the uterus, they become filled with blood. Like all processes, this one is related to hemodynamics. Then, most likely, discharge will be observed:

  • brownish;
  • pink.

There is no need to be afraid: this is the norm. After about a week, there will be a yellowish and transparent appearance. This is also the norm for a period of 3-4 weeks and even until birth. If a woman is absolutely sure that fertilization has occurred, and the discharge is painful, brown or red, profuse, and unlike menstruation, she should immediately consult a doctor or emergency room.

A woman who wants to have children can read any signal that her body gives her. It is important to remember that for many, ovulation is accompanied by copious, always clear, discharge. This happens due to the hatching of the egg and its journey through abdominal cavity. But if during auspicious days At conception, the discharge is white and cheesy - this is an alarming and dangerous signal. So there is fungal disease, are coming inflammatory processes. You should immediately make an appointment with a gynecologist.

Still, doctors do not perceive this method of determining pregnancy before a delay by discharge as effective and informative. Simply because the discharge means the following: the early onset of menstruation or fertilization.

With iodine

Using this solution, more than one remedy has been invented to answer the question: how to determine pregnancy in the early stages. The result will be true when all conditions are met. Let's take a closer look at how a girl can determine long-awaited pregnancy in the early stages at home with iodine.

  1. You need to pee on a piece of paper, then drop a few drops of iodine solution.
  2. The test is carried out with the collection of liquid tests in the morning, on an empty stomach.
  3. If the girl is pregnant, the leaf will turn pink; if not, it will turn brown or blue.

Successful fertilization can be determined using iodine by another method.

  1. Pee in any vessel, drop iodine solution there.
  2. If the droplet retains its shape, sank, and then rose to the top, there is a high probability that fertilization of the egg has occurred.

But it is important to contrive so that it smoothly sinks into the liquid, then it will definitely disintegrate. Women have learned to determine pregnancy using iodine at home for a very long time. Up to 2 months of pregnancy, this method will help determine the presence of pregnancy in the early stages.

Soda

A long-awaited pregnancy before a missed period can be determined with soda. Since time immemorial, women have known how to check pregnancy at home using soda and have successfully used this method. But there is practically no scientific basis behind it.

  1. You will need a clean, sterile container, morning urine, and a spoonful of soda.
  2. Place a spoonful of baking soda into the test glass and observe the reaction.
  3. If she hisses, the result is negative.
  4. Nothing happens, the soda just precipitates - the answer is yes.

How does urine and soda help determine pregnancy in the early stages at home, why does this interaction occur? Urine carries harmful waste from all over the body. During the day, urine becomes more acidic due to what you eat. It is because of this that it is better to do it in the morning, when acidity is at a minimum level. However, other factors also influence this:

  • disease;
  • Lifestyle;
  • duration of last sleep;
  • hygiene;
  • volume of water consumed.

The soda method is extremely controversial for determining pregnancy in the early stages, but it helps the impatient to find hope.

How to find out your gestational age at home?

One who actively plans her future pregnancy, must study your body in great detail, the symptoms and signals of the body, know what medicines are strictly contraindicated. Therefore, it is worth studying in detail the process of the appearance of the egg and its further movement through the body and how long it takes to determine pregnancy after conception.

This process is repeated for each healthy woman monthly:

  1. It all starts with PMS.
  2. The old egg is released and the new one begins to mature.
  3. The process is completed, the next step is ovulation.
  4. The process is started with the help of a special hormone - luteinizing hormone. Its highest content in urine occurs a couple of days before readiness for fertilization. It is he who enters into the reagent with tests to identify favorable moments for conception.
  5. There is a peak: this is a specific day. Fertilization can occur several days before and after day X.
  6. Next, the follicle becomes yellow body, begins to secrete a hormone that prepares the uterus to accept the fetus.
  7. When fertilization and implantation of the egg does not occur, exfoliation of the endometrium of the uterus begins - menstruation.

Having learned all this, the girl understands how to determine the duration of pregnancy at home. Important: menstruation is considered over when there is no trace of discharge. A woman can also find out almost the exact date of pregnancy at home.

Now we need to figure out how many days later pregnancy can be determined after ovulation. Ovulation occurs in the middle of the menstrual cycle. The menstrual cycle is 28 days, then the 14th day from the beginning of the last menstruation becomes favorable. You can start counting from there. Conception will occur at peak.

The peak lasts one day. Fertilization has occurred, now how to determine pregnancy in the first days after conception. multiple pregnancy in the early stages.

  1. You need to check with close relatives whether there is a genetic likelihood of twins. This is often inherited.
  2. A sure sign of twins is nausea from the first day of conception. This disease can bypass a single pregnancy, but not twins and triplets. And it lasts for almost 4 months.
  3. Plus big increase in weight, drowsiness and extreme irritability.

A pharmacy pregnancy test may show two bright, clear stripes even before the delay. After all the calculations and keeping these records, the girl knows exactly how many days pregnancy can be determined after conception.

Determining pregnancy in the early stages is not so easy. This video is for those who want to learn about the first signs of pregnancy in the earliest stages:

Conclusion

  1. Having read the article and familiarized herself with all the nuances, the girl now knows exactly how to determine pregnancy before a missed period at home.
  2. You can try to determine pregnancy a few days after conception.
  3. The fertilization process depends on the characteristics of the organism and takes from two to seven days.
  4. The girl needs to be a little patient. Of the above methods, the most accurate, scientifically based and practically error-free is the method of determining basal body temperature. Because the girl will be based on exact numbers and medical reports.
  5. For a woman, pregnancy is a moment of self-discovery. It is important to take care of yourself and avoid major stress!

Having learned about pregnancy, any woman will want to figure it out approximate period to schedule a visit to the doctor, registration with antenatal clinic and, of course, start preparing for significant event in my life - giving birth.

It is not difficult to calculate it, you just need to understand how to do it. It’s easy to find out if you remember the start date of the last cycle, that is, the last menstruation, and count the weeks from it. This period is called obstetric. On the Internet you can now even find special services that calculate the duration of pregnancy in accordance with the start date of the last cycle and its average duration.

But if the cycle is unstable and changes frequently, this method can hardly be called reliable, so a natural question arises about how to find out the exact duration of pregnancy.

You can find out the period quite accurately by using the new generation, which will especially help in the early stages, at the very beginning of pregnancy. Such tests determine the concentration of beta-hCG, a hormone that begins to be produced, and give an approximate result.

An obstetrician-gynecologist can also tell you how to find out the duration of your pregnancy. As a rule, doctors use two methods: a blood test for a special indicator, beta-hCG, and ultrasound.

A blood test, especially if done closer to 10-12 weeks, may not give enough information. exact result, since at these deadlines the boundaries of the norm are already too wide to set the deadline exactly. But ultrasound can give results more accurately even obstetric period. Measuring the size of the fetus and comparing them with a table of norms helps to establish the period very accurately, however, it is called embryonic and is often slightly behind the obstetric one. At the same time, the doctor can tell you how to find out the due date; it is not difficult to calculate it.

There are several other ways to find out your gestational age. For example, you can learn to measure by asking your doctor to show you how to do it. It will be difficult at first, but as the uterus rises, it will become easier to take measurements. Normally, this value is equal to a week of pregnancy.

There is a method that even doctors focus on - the time when the expectant mother begins to feel the fetus moving. This usually happens in Some pregnant women even believe in the superstition that by counting exactly 20 weeks from the moment of the first movements, you can find out the date of birth.

The closer the end of pregnancy is, the easier it is to determine its exact duration using ultrasound. While in the early stages it could interfere or not be enough good equipment, then now that the baby is already big, it’s easier to measure him.

You can ask different doctors how to find out the duration of pregnancy, but only the woman herself can accurately answer this question, focusing on her own feelings and well-being.

It should be remembered that in most cases, babies are not born exactly on time, but earlier or later by several days, or even two weeks. This is considered normal, so there is no need to worry. But you should definitely take into account that the due date given by the doctor is only an approximate date, so it is better to prepare for childbirth in advance.
