Pregnancy Calculator

Babies usually come when they are ready but this little pregnancy due date calculator below can help give you an indication of your due date based on a 'standard' 40-week pregnancy. In general, healthcare providers use the first day of your last menstrual period (LMP) to determine your due date.

Always consult your healthcare provider to determine your correct pregnancy due date.

Your healthcare provider will be able to give you the most accurate due date for you, based on individual factors that may affect you and your pregnancy.
