Calculate your estimated due date using our due date calculator. Insert the date of the first day of your last menstrual period in the Due Date Calculator along with the length of your average cycle.
How is your due date calculated
Your pregnancy is calculated from the first day of your last menstrual period rather than the date of conception. As women can varying in the length of their menstrual cycle, this can affect the due date. For example, a woman with a 35 days cycle will be due approximately 7 days later than a woman with a 28 day cycle.
You will be advised of your due date during your first appointment with us.
