Dear user. I can understand. 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. Take care.

Your due date is calculated by subtracting 3 months from the 1st day of your last menstrual period (LMP), then adding 7 days ? that's your due date the following year. For example, say your last period began on April 11. Count backward 3 months, which gets you to January, and then add 7 days.
