How to calculate your
estimated due date of delivery
The method most frequently used
is the one that assumes the conception occuring 14 days after the start of the last
menstrual period.
The approximate date may be obtained by taking the date when your last
period began, adding 7 days, then counting back 3 months and add a whole year.
For example, if the first day of your last period was September 9, 1999; add 7 days and
you get September 16,1999; then count back 3 months and you have June 16: the estimated
due date is June 16, 2000
Even though this is a good
method to obtain your due date, REMEMBER
that these are just ESTIMATED dates. In some cases your doctor can apply more reliable methods, such as:
knowing the exact date of ovulation, measuring the size of the uterus by a clinical
exam, ultrasound (during the first half of pregnancy, ultrasound can estimate the
age of fetus within 7 days).
