Pregnancy Due Date Calculator

Your due date is typically calculated based on the first day of your last menstrual period (LMP). Pregnancy is 266 days from conception, or about 280 from your LMP. This is 40 weeks or 9 months (give or take a few days). If you don't know when your last period was, your doctor or gynaecologist will use an early ultrasound to help you determine your due date. The ultrasound is more accurate the earlier it is done.
