In a woman with the average, 28 day cycle, ovulation generally takes place between cycle day 12 and 14, though early and later ovulation can occur. Cycle days are counted from the onset of menses.
There is no typical ovulation day. Every females body is different and ovulation will vary from person to person and can vary from cycle to cycle. For the most part ovulation occurs 10 to 15 days before the start of your period. Not after it starts but before it starts.
