Estimate your baby's due date and track your current week of pregnancy based on your last period.
Due Date = LMP + 280 DaysPregnancy is a 40-week journey that is usually measured from the first day of your last menstrual period (LMP). While only 5% of babies are born on their exact due date, having an anchor point is essential for medical prenatal care.
