A member asked:
Hi i i had my last period on sep 25- 30 and i am pregnant now with a 31 day cycle. when was i likely to ovulate?

About October 12: In real life, nobody knows exactly when she ovulates. The estimate is done by subtracting 14 days from the cycle length of 31 days, and adding the result (17 days in this case) to the start of the last menstrual period (sept. 25 in this case). So, sept. 25 plus 17 days is oct. 12. It's just an estimate, as there is no way to tell exactly.
