Hi doctor, why does PCOS cause irregular periods and intermenstrual bleeding?
Regular menstrual periods are associated with regular ovulatory cycles. You have a period 14 days after you ovulate. For example, if your period comes every 28 days, you ovulate on day 14. If your period comes every 30 days, you ovulate on day 16. Many women with PCOS don't ovulate regularly, hence they have irregular periods.
