Cycle length

days

The typical length of a pregnancy is 40 weeks, or 280 days, from the first day of your last normal menstrual period. If you know that date, then you’re set: just add nine months and seven days to it, and you’ve got a due date!

This is just an educated guess, however, based on the average 28-day length of a menstrual cycle. It’s estimated that less than 5% of pregnancies are delivered on their predicted due date, and if your cycle is typically longer or shorter than 28 days, this will affect your date.
