Well, the best time to conceive is at the time of ovulation. Ovulation in the female cycle is usually at the midpoint between two menstrual periods. We consider the menstrual cycle or the ovulatory cycle as the first day of one menstrual period to the first day of the next menstrual period; that's considered the menstrual interval or the ovulatory cycle. The classic ovulatory cycle is usually a 28 day cycle from the first day of one period to the first day of the second period. On a 28 day cycle, on average at about day 13 or 14 is when the woman will ovulate. And so couples that are trying to conceive should focus intercourse on day 13 or day 14 in a 28 day cycle. But a lot of women have a 35 day cycle, which is normal for them. In that case, it's gonna be about day 18 or 19 that they're ovulating, and then as late as day 20. So the interval between menstrual periods determines when ovulation and when conception take place. And the easy rule of thumb is just to kind of take half the distance between the periods. If it's a 35 day cycle, then it's day 17, 18, 19, somewhere in there. If it's a 28 day cycle, then it's day 13 or 14.
