The normal gestation period is 40 weeks from the date of the
last menstruation.
The estimated date of birth can be added 7 days to the date
of the last menstruation and can be calculated practically by going back 3
months. Here, the estimated date of birth is the last date when birth can
occur. Most births do not wait until this date, they take place between 38-40
weeks. Sometimes, people who pass the day may pass this date for 1 week. That
is, the birth estimate often happens 1-2 weeks before the result calculated by
the date of birth.
Sample:
The estimated date of birth of someone whose last menstrual
date is April 10
10 + 7 = April 17
From April -> 3 months back January -> January 17.
Sample:
For someone whose last menstruation date is February 5:
5 + 7 = February 12
3 months back from February 12: The estimated date of birth
is November 12
However, this method may cause errors especially in people
whose periods are irregular. In this case, the estimated birth date is calculated
using the ultrasound measurements.
