here to find your due date.
This interactive tool
calculates your pregnancy due date, an estimate of when you are likely to
deliver your baby.
To find your due date, the calculator takes the
first day of your last menstrual period (LMP) and adds 40 weeks. If you are
planning a pregnancy, you can use this calculator to plan the birth for a
certain month or season.
Health Tools help you make wise health decisions or take action to improve your health.

estimate of when you will likely have your baby, based on the normal length of
