But this study should be carried out in any case, because thanks to it you can find out about the condition of the child, as well as identify various pathologies in the first weeks. An experienced gynecologist can determine the week of pregnancy by the size of the uterus. A blood test for hCG will help to say more accurately about the expected duration of pregnancy. The level of this hormone is constantly changing in each period of bearing a child. And depending on the amount of the substance, you can find out quite accurately what week of pregnancy a woman is in. And already based on this data, calculate the date of the expected birth.

How to calculate pregnancy yourself

You can also determine the expected date of birth at home. Moreover, this can be done in different ways:

Determining the moment of conception.This method is suitable for women who know exactly what day the sexual intercourse that led to pregnancy occurred. This is possible if the woman monitors her ovulation and knows when it occurred. In this case, the error can be 2-3 days.
On the last monthly. This method is quite accurate, especially if the future mother had a menstruation calendar. From the last day of the month and until the expected delivery will take 280 days.
The baby's movements.During the first pregnancy, the baby begins to "beat" at about the 20th week. If this is not the mother's first child, then it will make itself known already at the 18th week. But such a method is not accurate enough, because the baby's first kicks can be confused with intestinal peristalsis.
Online calculator.There are many programs on the Internet that can help a woman determine the week of pregnancy. Of course, in this case there is a small error of 2-3 days. But otherwise, the calculators are quite accurate, because they calculate the days of pregnancy according to all the rules of obstetrics. In addition, such programs are often supplied with a special calendar. It describes in detail what the expectant mother may experience in this or that period of bearing a child.

There are many methods by whichthe expectant mother will be able to calculate the term of her pregnancy, as well as find out the expected date of birth. Moreover, it is not necessary to go to an unscheduled appointment with a gynecologist for this, because you can comfortably do the calculations at home.
