The most common way to calculate your due date is by counting 40 weeks from the first day of your last menstrual period LMP. This method is based on the idea that women typically ovulate about 2 weeks after their period starts and pregnancy typically lasts about 38 weeks. If you happen to know the day you conceived, you can calculate your due date by counting 38 weeks from that date. You can tell when you conceived if you know when you ovulated - say, if you were using an ovulation predictor kit or tracking your ovulation symptoms. Sperm can live for up to 5 days inside your body.
