When did you conceive if your due date is December 30?

To calculate the approximate conception date, we can subtract 280 days (40 weeks) from your due date.

Conception Date: March 17

This calculation assumes a typical 28-day menstrual cycle and that ovulation occurred 14 days before your last menstrual period. However, it's important to note that conception dates can vary depending on an individual's cycle length and ovulation patterns.
