Most of the fair sex is looking forward to the two cherished stripes. And now, as soon as they find out that everything turned out, they have a question: from what day do they consider pregnancy? Unfortunately, it is almost impossible to determine to the accuracy of the day. The only exception is the constant monitoring of ovulation. But it is carried out only during infertility. But there are other ways, which help is more or less correct calculation of the gestation period. This is medical research, calendar methods, gynecological examinations. We will understand what are the existing types of determining the period of an interesting position of a woman.

We consider carefully

Someone believes that the stork's waiting time is the amount of time that passes from the moment of conception. This point of view takes place, because it is quite true. Only in this case is meant the term embryonic. Usually its duration is 38 weeks. But after all, a karapuzik can ask for this world a little earlier or a little later.

On what day is pregnancy considered? How correctly to count pregnancy on weeks

Modern medicine takes into account not the embryonic term of pregnancy, namely obstetric. Its peculiarity is that the first day of the last monthly period is used for counting. This will be the first day of pregnancy. When a woman becomes registered, the doctor enters this date on the exchange card and relies on it when calculating the time limit.

It is known that ovulation occurs approximately in the middle of the cycle. That's because of this it becomes clear from which day the pregnancy is considered by doctors. And so the difference between obstetric and embryonic gestation is exactly two weeks (the first term is more than the second). In the first seven days, the egg begins its maturation and preparation for fertilization.

Oh, these forty weeks!

Usually the pregnancy lasts 40 obstetric weeks. But the appearance of the baby on the dates from the 38th to the 42nd week is also considered the norm. Formally, pregnancy can be considered premature or delayed, but in fact the birth takes place at a time determined by nature - just in time. Here, of course, the question arises: what day is pregnancy considered? And such interest is understandable, because the discrepancy in the dates is that the calculated midwifery period is very average. With embryonic he can coincide only when the conception of the baby occurred in the middle of the 28-day cycle. And that provided that the cycle before pregnancy was regular.

In addition to the usual calculations with the help of the calendar, the doctor can set a deadline, taking into account the data of ultrasound diagnostics. This will be possible only if the future carp is developing according to all the terms of pregnancy.

If the expectant mother believes that the conception did not occur in the middle of the cycle, as it happens in most cases, but shortly before its end or at the beginning, it is obliged to inform the gynecologist about it. Then the doctor will correct his calculations to determine as accurately as possible PDR (the preliminary date of birth).

Method calendar

This method is designed to control every sexual act. If the union of bodies does not happen so often, the woman will necessarily understand at what day fertilization occurred. Some potential mothers have taught themselves to measure basal temperature. If they have learned to use the schedule correctly, they should tell their doctor about the day they are taken out. Based on this information, the doctor will set an approximate date with an error of two weeks.

From what day do you consider pregnancy in this case? The error is based on the fact that people in white coats take into account only obstetric term, the feature of which is its dependence on the first day of the last month. This is a very accurate technique, and the date of delivery is set to within a week. And you can calculate by a simple formula, which is for certain known to many: the actual day of fertilization + 280 days. Or, from the day of conception, take three months and add seven days. If the potential mother knows the exact day of her ovulation, then by the day of conception, only 264 days should be added. This too will be the right result.

Such familiar and promising ultrasound

For many years, ultrasound has been used to monitor the development of the fetus in medicine. After all, every future mother is very concerned about the question of how to correctly consider pregnancy. And with the help of ultrasound can be calculated as an approximate period of conception, and childbirth. To get a more accurate result, doctors recommend that a woman be examined in the first 8 weeks. It is at this stage that each fetus develops in exactly the same way. By its size and the term is determined.

But further development of each future karapuzika occurs strictly individually. Body parts and organs can develop slower or faster than suggested by the regimens. From this we can draw a simple conclusion: the less the gestation period, the better and more effective will be the examination response. The result the doctor compares with the data in the table and verifies the week of pregnancy. If ultrasound will detect a delay in the development of the fetus, then a diagnosis will be made about it. And the only thing that will be able to speed up the development of the baby is that the future mother will be very attentive to her health.

At a gynecologist's appointment

Some women make mistakes when arriving at the gynecologist on the first day of the delay, hoping that only he is able to tell if the pregnancy has come or not, and if the answer is positive, determine the first day of pregnancy. But at this point it is impossible to determine. Yes, the uterus will be slightly enlarged, but this may be due to future menstruation. And its increase, associated with the beginning of a new life, will occur only after the second or third week of delay. The size of the uterus at this stage will be with a chicken egg. The peculiarity of examinations at a gynecologist is the same as for an ultrasound: the shorter the time, the more precise the exact date of conception will be determined.

Pregnancy with IVF

With each passing day, the number of women who decide on artificial insemination increases. This method assumes that the egg will be combined with the sperm, after which the specialists will observe them for several days. And here, a woman who exposes herself to such a procedure, has the right to ask, from which day the pregnancy with IVF is considered. And everything is easier than it may seem: the embryo is planted not earlier than in three or five days. That's when the pregnancy begins.

If a woman has a short cycle, the obstetric term is set from the day of the last menstrual period. And if it's long, there will be some features. A potential mother will start taking medications that block the activity of the ovaries (their stimulation will begin later). Therefore, if you count from the last menstruation, then in the real world the development of the fetus will be 3-4 weeks, and the calculated period is 7-8 weeks. Therefore, there is no problem to understand from what day the pregnancy is considered - from conception or implantation. Gynecologists are counting from the day the embryo is inserted into the woman's body.

Getting ready to give birth to a healthy baby

Instead of disputes with the doctor about the situation from which day people in white robes feel pregnant, the future mother should better direct all her attention and care to the new life that is growing in her. After all, for the development of crumbs, it is important not only the physical health of the mother, but also the psychological one. A woman should try to experience more positive emotions, often breathe fresh air, eat more vegetable food, consuming many seasonal vegetables and fruits.

The state of pregnancy is one of the most joyful moments in the life of every woman. She must try not to spoil his joy from the expectation of the baby. The future mother should simply enjoy her current position, rest more and remember that the child is happy only when his mother is happy.
