Week-by-week pregnancy guide

Week 1

You

Your pregnancy officially begins on the first day of your last period. It’s a bit confusing, because you haven’t conceived yet and like most women, you probably don’t know when you ovulate. However doctors use this method to date your pregnancy because studies have shown the average duration of a pregnancy is 280 days from the first day of the last normal period.
