How Are Due Dates Calculated?

Using birth control methods such as pills as prescribed by your gynecologist is an effective way to prevent unintended pregnancies. But it’s important to remember that it’s still possible for an unintended pregnancy to occur, especially if you miss a few days of pills. If you think you might be pregnant, you should see a gynecologist right away for a lab test. The estimation of your due date will be a significant factor in determining which type of pregnancy termination is available to you.

Watch this video for an introduction about calculating due dates. This doctor explains that your due date is calculated from the first day of your last period. From this point, you can count 280 days forward to arrive at an estimated due date.
