Due Date Calculator

Calculate your estimated due date using our Due Date Calculator. Insert the date of the first day of your last menstral periodin the Due date Calculator along withn the length of your average cycle.

How is your due date calculated?

Your pregnancy is calculated from the first day of your last menstral period rather than the date of conception. As women can vary in the length of their menstral cycle, this can effect the due date. For example, a woman with a 35 day cycle will be due approximately 7 days later than a woman with a 28 day cycle.

Sarah will advise you of your due date during your first appointment.
