Will I deliver on my due date?

The duration of the average pregnancy is 40 weeks (280 days). The emphasis is on the word “average.” Only about 4% of all women will actually deliver on their due date. However, over 90% will deliver within two weeks of that due date. If you should go more than one week past your due date, other tests may be performed. If this situation arises, it will be discussed with your doctor.
