Figure out the first day of your last menstrual period. If you have a normal 28-day cycle, use simple math to determine your delivery due date. Add seven days to the first day of your last menstrual period. Count back three months. Add a whole year. Your result is your due date. A simpler method is to add 281 days to the day of your last menstrual period.

Use a formula that adds 267 days to the date of conception. For example, if you conceived on January 1, 2008, add 267 days and your estimated due date would be September 25, 2008.

See a doctor. Estimating your delivery due date based on simple math or online calculators are only estimates. To determine a more accurate due date, visit your doctor and have a pelvic exam and an ultrasound performed. A doctor can measure the size of your uterus during a pelvic exam and can determine the age of your fetus with an ultrasound. This information is more reliable in determining your due date.
