Pregnancy Calculator

Our pregancy calculator will help you determine your due date. Simply enter the date of your last menstrual period and click on the calculate button below.

Keep in mind that this calculator is based on a 28-day menstrual cycle, and may need to be adjusted for women whose cycle differ from 28 days.

Your due date is estimated by adding 40 weeks to the first day of your last menstrual period. Only 5% of women deliver on their projected due date, so this date should be used as an estimate, not an exact calculation.
