Calculate Your Due Date
Questioning when your baby is due?
The Mommy Playbook’s due date calculator will calculate your estimated due date based on either the first day of your last menstrualperiodor,if known, your ovulation date.
Along with the due date, the calculator will calculate the estimated start date of your second and third trimesters.
How to get started:
Enter the date of your last menstrual period. For more accurate results, you’ll want to use the first date you started bleeding. If you know the date you ovulated, you can enter that date into the Estimated Date of Ovulation field instead.
Be sure to check with your doctor or midwife for specifics as this calculator is for estimate purposes only. It assumes a cycle length of 28 days and a luteal phase of 14 days.
