29-31d; day 15-17: I looked at your menstrual history, and your cycles were all between 29 and 31 days long. You count from the 1st day of bleeding, to the following cycles 1st day of bleeding. Ovulation occurs 14 days before the menstrual cycle starts, so your ovulation occurs on day 15 (when the cycles are 29 days apart) on day 16 if they are 30 days, and day 17 for 31 day cycles. Plan accordingly! ;-).
