The time of ovulation usually occurs midway between first day of two successive periods, but it can vary from day 8 to day 20 of a 28 day cycle. Figuring the Odds of Being Pregnant. The middle two weeks of your cycle is the time you are most likely to get pregnant. Most women ovulate around day 14, but there is great variation. The time of highest risk for unprotected sex is one or two days before ovulation when there is a 30% chance of becoming pregnant. Three days before ovulation the risk is 15%; on the day of ovulation it is 12%; after ovulation the risk approaches zero. Women with irregular cycles have more trouble determining when ovulation is occurring.
