Welcome to the Pregnancy Calculator, a free service from Dr Penman at Fetal Medicine UK.
HOW TO USE THE CALCULATOR: Enter the date of the first day of your last period. The calculator will estimate your due date, as well as the date ranges when you should go for the various scans throughout your pregnancy, such as your 12 week Nuchal With Early Gender Scan.
PLEASE NOTE: This calculator assumes you have regular cycles of average length (28 days). If your cycles are longer or shorter than this, you should adjust your predicted scans and due date accordingly. You may also find that the calculator doesn’t work for you. This is because Ad Blocker prevents this calculator from working properly. If you experience problems with this calculator, try disabling your Ad Blocker and refreshing the page.
