Dont worry our tool will do those sums for you, just fill in your info below and the results will show on our calendar. Pregnancy normally lasts from 37 weeks to 42 weeks. Pregnancy is counted as being 40 weeks long, so your due date is calculated at 280 days from conception. Unless you can pinpoint exactly what point of your ovulation cycle you were in at the time of fertilization, it’s difficult to know how far along you are and what date you’ll meet your baby. To find your due date, enter the date of the first day of your last period, and select show your due date. That means that simply estimating nine months from the day you take a pregnancy test isn’t going to calculate your due date, and, even so, factoring in a few weeks here and there for ovulation won’t either. Many won’t be aware of their pregnancy until their first missed period, and by that time they could be up to five weeks in. Most expectant mothers don’t realize that both menstrual and ovulation periods count as the first two weeks of pregnancy.

While it’s true that most pregnancies last 40 weeks, there are other factors at play which will determine your due date.
