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!
Ovulation usually occurs between day 11 and day 21. Each woman ovulates on her own schedule. You've probably heard that ovulation occurs on Day 14 of your cycle, but that's not necessarily true. In fact, even women with 28-day menstrual cycles don't always ovulate on Day 14. One study found that fewer than 10 percent of women with 28-day cycles were ovulating on Day 14. Usually, when a woman says she is ovulating, she's referring to the especially fertile period of two to three days that precede ovulation.
