About 10%: Almost all natural pregnancies result from intercourse during the six day interval ending on the day of ovulation. The probability of pregnancy is greatest on the day of ovulation (33%) and decreases as the time between intercourse and ovulation increases; it's about 20% 3 days before ovulation and about 10% 5 days before the day of ovulation. If you do ovulate on nov 30, it would be about 10%.
