Polycystic Ovarian Syndrome & Birth Control.?

PCOS is a very complicated condition and causes infertility in many women. Generally once you get off birth control your body will revert back to the irregular cycles after the levels of hormones are no longer being controlled by the BC. I think this is the window she is referring to. Most doctors I have gone to say that yes, it is right after you get off BC that you are most fertile, so if you are planning I would be do ovulation tests starting the day after you have the ring removed and continue each day until you see a positive sign. It is possible even on BC you will not have ovulation because of the PCOS. Good Luck to you though.
