In a human pregnancy,Childbirth usually occurs how many weeks after conception?  is it 38 or 42? I am totally confused?

When speaking about pregnancy, you usually say that the gestation period is 40 wks long, but the count starts on the first day of the last menstrual period, which means by conception you are about 2 weeks pregnant already. So around 38 wks would be a more accurate if you are counting from conception.  But, full term is considered anything between 37-42 weeks, with best being right around 40 wks.

The expected date of Delivery or EDD is calculated by an equation:
The date of the last normal menstruation + 7 days and 9 months to give 40 wks gestational period. But, normally the EDD ranges between 38 and 42 weeks.

It averages 40 weeks, and many first time pregnancies run a little longer much to the irritation of the mother-to-be.

40 is normal, but babies are considered full term if born between 38 and 42 weeks.
