Other factors (e.g. stress) can result in ovulation being delayed, until as late as the third or fourth week. However, the way our care providers calculate pregnancy due dates is by assuming ovulation on day 14 of a 28 day cycle. You can already see a major reason why due dates aren't so accurate!
This includes the day of ovulation and the 5 days before it. On average, ovulation occurs 12 to 16 days before the menstrual period begins. So ovulation would occur on about day 10 of a 24-day menstrual cycle, day 14 of a 28-day cycle, and day 21 of a 35-day cycle.
