For contraception?: The couple avoids having sex during her fertile days, and prays that her ovulation day is exactly when they guess it will be, every month of every year. In a 28-day cycle, ovulation should be day 14, so avoid sex without a condom from days 8-17 (to be safest). The most fertile days are days 11-15. The fertile days are a little different if the woman has cycles longer or shorter than 28 days.
