At what time of the month is a woman fertile?
The most fertile time of the month is just before or the day ovulation. Ovulation usually occurs two weeks before a period starts, so it is necessary to count backwards from the anticipated start of the next period in order to find the most fertile time. Take the number of days in the usual cycle (from the beginning of one period to the beginning of the next) and subtract 14. For example, a woman with a 32 day period would likely ovulate around day 18 (32-14=18), while a woman with a 28 day cycle would ovulate around day 14 (28-14=14). We recommend every other day intercourse around the day of ovulation. That would mean days 12, 14 and 16 for women with 28 days cycles.
