How can I calculate my EDD?
Your due date is calculated by adding 280 days (40 weeks) to the first day of your last menstrual period (assuming a 28 day cycle). Note that your menstrual period and ovulation are counted as the first two weeks of pregnancy. If you deliver on your due date, your baby is actually only 38 weeks old, not 40. Please remember that your due date is only an estimate. Every pregnancy is unique and your baby will come when it's ready. Be sure to talk to your doctor or OBGYN about your due date.Read more
