after how many days from ovulation your period start
There is not a way to know for certain how long after your period you will ovulate, however. Ovulation does not occur in relation to the previous period, but rather to the next period. You will ovulate 14 days prior to the start of your next menstrual cycle. This means, then, that if you have a 28-day cycle, you will ovulate roughly 14 days after your period, and 14 days prior to the start of your next period. If you have a 31 day cycle, however, you will ovulate roughly 17 days after your period, and, again, 14 days prior to the start of your next period. If you are trying to conceive, you should begin to have intercourse roughly 4-5 days prior to ovulation, as the sperm can live in the body for about 5 days.
