On the question of what day your child will be born, no one can answer with absolute accuracy, since it is simply impossible to take into account all factors affecting the course of pregnancy.

A normal pregnancy lasts 280 days, or 40 weeks, which corresponds to 10 lunar months (for 28 days), or approximately 9 months on a calendar. However, at present it is considered that starting from the 38th week the child is already full. Later birth of crumbs (after the 40th week) is also considered normal. Births are caused artificially after the 42nd week.

Methods for calculating the period of delivery.

There are several ways to calculate the probable period of childbirth.

On the day of menstruation. The estimated term of delivery is calculated as follows:.

By the date of the first day of your last menstruation, add 7 days. From this date, count back 3 months and add 1 year.

For example, your last menstruation began on May 12, 2005.. Add 7 to 12 and count back 3 months. Your intended delivery date is February 19, 2006..

On the day of fertilization. This way of counting "works" only when you are sure that the sperm penetrated into the egg on a certain day. Then from this significant day you need to take 3 calendar months and you will get a probable day of childbirth.

On the first movements of the fetus.

In the middle of pregnancy you will feel a stir. Mark this day in the calendar. To the marked date, add 4.5 calendar months, and you will get a probable day of childbirth. Bear in mind that with repeated pregnancies, women experience fetal movements at week 18, and at the first - at week 20-22.

The height of the standing of the uterine fundus above the womb and the volume of the abdomen. These measurements are carried out by a doctor using a centimeter tape or tasomer - a special tool. During the measurement you will need to lie on your back. Measures the distance between the womb and the probing bottom of the uterus. Thus, in normal pregnancy, the height of the standing of the uterine fundus above the womb is 6-7 cm in the fourth (lunar) month, 12-13 cm in V, 12-24 cm in VI, 24-28 cm in VII, VIII - 28-30 cm, on IX - 32-34 cm, on X - 28-32 cm. And keep in mind that during measurements your bladder should be emptied, otherwise the data may be distorted by health. Sumy. Ua.
