Ovulation and Becoming Pregnant

Data gathered on ovulation shows that it most often occurs between 8 and 19 days after the onset of menses, the exact day being influenced by the length of the individual menstrual interval. Whether you have a short menstrual interval (for example, 25 days from the first day of bleeding to the next first day of bleeding) or longer intervals (31 to 35 days), you will ovulate about 12 to 14 days before the onset of your next menstrual period.When an egg is fertilized, however, there is no next menstrual period, ovulation occurring about 14 days before the woman would have menstruated had she not become pregnant.
Since most women menstruate approximately every 28 days, if one counts the first menstrual day as day one, the usual time of ovulation is day 13 or day 14, which explains the fact that pregnancy is most likely to occur in midcycle, midway between menstrual periods. In very rare instances, however, pregnancy may result from intercourse at virtually any time during the menstrual month which implies that ovulation in exceptional cycles occurs at exceptional times. There is evidence that female orgasm infrequently may trigger an abeltant ovulation in some women. All experienced clinicians can site examples of women becoming pregnant at odd periods in the cycle. Anecdotal reports of pregnancies being established during menses and very early and very late in the non bleeding part of the cycle abound. In truth, such pregnancies are quite rare.
The two times in the month when pregnancy is least likely to occur, the relatively “safe periods” for sexual relations without causing conception, are the first week of the cycle including the menses, and the last week, that is, the week prior to menstruation.
