Use this handy calculator to find out the due date of your baby. Simply enter the date of the first day of your last menstrual period and the myDr calculator will tell you the approximate due date of the baby's birth. Remember that the normal range of time betwen conception and birth can vary from 38 weeks to 42 weeks, depending on your menstrual cycle and the date of your last period. This myDr calculator uses the method used by doctors, where the due date is 280 days from the first day of your last period. Ultrasound scanning can provide a more accurate determination of your baby's due date, so ask your doctor when you have your first ultrasound.
