Your due date is an estimated date of when your baby will be born. This is based on the length of an average pregnancy — 280 days or 40 weeks from the first day of your last period.
Using this method of calculation and assuming that you conceived on the 14th day of 280 days, you weren't officially pregnant during the first two weeks of your pregnancy. You may also be surprised to learn that you are very unlikely to give birth on your exact due date. In fact, the chances of this happening are only 5 percent! You are, however, extremely likely to have your baby within two weeks on either side of this date, because a normal pregnancy can last between 37 and 42 weeks.
A Handy Due Date Formula:
- Start with the first day of your last period and count backwards three months to get the month in which you will deliver.
- Add seven to the day of the month in which your last period began to get the due date.
- For example, if your last period began on August 20, you would count backwards three months to May. Then, add seven to 20 to get a due date of May 27.
