Q: When does ovulation occur and when is the best time to have intercourse in order to conceive?
A: The length of the menstrual cycle (the time from the start of one period to the start of the next) varies from person to person. Anything from 21 - 35 days is normal. On average, most women have cycles of about 28 days. In this case, ovulation occurs on Day 14. If your cycle is not 28 days, the way to work out the time of ovulation is to subtract 14 days from your cycle length, i.e. for a 30 day cycle, ovulation should occur on Day 16 (30-14). The best time to have intercourse would be starting two days before the expected ovulation to two days after. Bear in mind that not all women ovulate at the expected time, so this is not an absolute rule. Unless you are having difficulty conceiving, regular intercourse about three times per week will catch the ovulation period.
