When does ovulation occur?

            In an average 28-day menstrual cycle, ovulation occurs about 14 days before the beginning of your next menstrual period. The exact timing varies — your cycle length may be longer or shorter. You may find it helpful to track your menstrual cycle using an app on your phone or a calendar. This can help you determine when ovulation is most likely to occur. Most people will have a period 14 to 16 days after ovulation, regardless of the length of their overall cycle.
