This can be difficult to predict, but ovulation typically occurs approximately 12-16 days before a womanâs next period begins. Most women have cycles that are in the 26-32 day range and so for most women, ovulation happens around the midpoint of their cycles.
The first day of menstruation marks the beginning of a new cycle, two weeks after which another ovulation occurs. This occurs 11-13 times a year, and menstrual cycles may normally vary to be as short as 21 days or as long as 35 days. The duration of a normal menstrual period may also vary among different women.
