How do you know if your ovulating if you have pcos?

Regular periods: Regular periods are invariably a sign of ovulation. If your periods are erratic and less frequent but normal when they come you are probably ovulating. A simple method you can use is to track your morning temperature, your "basal body temperature." after ovulation your baseline temperature will rise 0.3 or more degrees f, and stay elevated until your period comes (or longer if you are pregnant).
