Due Date Calculator

Due Date Calculator

After a positive pregnancy test, quite often the first thought is, "When is my baby due?" Pregnancy due dates are 40 weeks long, based on the assumption that a pregnancy is 9 calendar months. The due date is calculated from the first day of a woman's last menstral period. Conception typically happens 2 weeks after this time (or two weeks before the woman's next period is due). Find more details on due dates here. Use our Due Date Calculator to help you calculate your due date in a matter of seconds.

Once you've figured out your due date, head over to our due date groups and chat with other mums-to-be due in the same month as you.
