When precisely are you most fertile?
For the most advanced and accurate means of ovulation prediction, the American Pregnancy Association recommends the OvaCue Wireless Fertility Monitor from Fairhaven Health. This device easily and accurately predicts ovulation up to 7 days in advance and confirms when ovulation has occurred.
If you are trying to conceive, APA suggests having intercourse every other day in this window. If you are trying to prevent pregnancy, avoid sex within this window and the 3-5 days before, or at least ensure you are using a form of birth control consistently and correctly.
