Menstrual Cycle:
The Fertility Time Frame ?

In the average menstrual cycle, ovulation, or the release of the mature ovum due to luteinizing hormone (LH) surge, starts around cycle day 12 and may last 48 hours. The most fertile period, the time with the highest likelihood of pregnancy resulting from sexual intercourse, covers the time from some 5 days before ovulation until 1-2 days after ovulation.
