Pregnancy Due Date Calculator

Congratulations on your pregnancy! This calculator will help you determine your baby's due date. The only field required is the first day of your last menstrual period. The pregnancy due date calculator assumes a standard 28 day cycle with ovulation on day 14. If your cycle is normally longer or shorter than 28 days, enter your cycle length below and the calculator will adjust your estimated ovulation date accordingly.
