When is my Ovulation Date?

Your ovulation date is about 14 days after the first day of your last menstrual period. If your last menstrual period was on December 1, then your ovulation date would be around December 15. This is good to know if your are trying to get pregnant. If you are not trying to get pregnant, you might want to abstain or make sure you use a reliable method of birth control around that time of the month.
