DueDateCalc cannot answer personal medical questions and does not review individual dates or scans. For anything about your own pregnancy, please contact your healthcare provider.

If you spot an error in a formula or a date, a message with the page address and what you entered is genuinely helpful — the methods are meant to be transparent and correct.
