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!
That's why we use ovulation tests and chart fertility. In fact, normal ovulation can occur as early as day 8 or as late as three weeks into your cycle. When ovulation occurs is a coefficient of menstrual cycle length, so women with long cycles will ovulate later than women with shorter cycles.
