Patient discussion about expected date of delivery
Q. How many women actually give birth on their EDD (expected delivery date)? I am pregnant and my EDD is January 22nd. I was wondering what are the chances I will give birth on that day exactly?
A. If it's your first pregnancy, you probably will give birth after your EDD, as first pregnancies tend to be longer. Your EDD is after a full 40 weeks of pregnancy. It is most common to give birth between 38- 42 weeks of pregnancy.More discussions about expected date of delivery
