Often, pregnant women have difficulty calculating the expected due date. You can calculate when your baby will be born, based on several indicators that are guided by obstetricians-gynecologists.

Step 1

Date of last menstruation.

Obstetricians-gynecologists calculate the gestational age from the first day of the last menstrual period. Add 280 days to the first day of your last period to find your estimated due date.

If you know the date of conception, you should not be guided by it, since from the first day of the cycle, the processes necessary for the attachment of the embryo and its development begin in the uterus.

This method will allow you to calculate the date of the baby's arrival with maximum accuracy if you have a regular menstrual cycle of 28 days. In the case when the cycle is shorter, the expected date of birth is earlier, and if it is longer, later.

Step 2

Based on the results of an ultrasound scan.

During an ultrasound scan, the doctor uses special tables to determine the size of the fetus, their compliance with a certain period of pregnancy. According to the first ultrasound, the gestational age is determined with greater accuracy. At long periods of pregnancy, the size of the fetus fluctuates over a wide range. It also happens that according to ultrasound, the period is shorter due to a possible delay in the intrauterine development of the fetus.

Based on the results obtained, the doctor will determine the expected date of delivery.

Step 3

On the first stir.

You can determine the approximate date of birth of the baby by the first movement of it. Usually, a woman who gives birth for the first time feels the first movements of the baby at 20 weeks, if the birth is not the first - at 18 weeks. Add 20 weeks to the date of the first stirring if the first birth is coming, and 22 weeks if you have already given birth.

But you should not rely only on this method, since most women feel the first movements of the crumbs already from 15-16 weeks. In addition, this method is not objective, since a pregnant woman can mistake intestinal peristalsis for moving the baby, for example, or, conversely, take movements for peristalsis for a long time. But, in any case, remember the date of the first stir, as most doctors ask for it.

Step 4

Determination by first attendance.

The doctor can determine the exact period of pregnancy by the size of the uterus when examining you in a chair, if the first appearance was before 12 weeks of pregnancy.

As a rule, only a few babies are born on the day appointed by the doctors. The date of birth depends on the individual characteristics of the woman's body, as well as on whether the baby is ready to appear. Don't worry if you don't give birth on the scheduled day, a normal pregnancy can take between 38 and 42 weeks.
