Im confused. I havent had AF for 2 months going on 3 and im not pregnant. I even had a u/s done to make sure that there was nothing wrong with my womanly parts and everything is checking out normal. i know that sometimes antipsycotics can mess up your cycles (im on 2 of them) but i didnt know that it could make your AF be 2 months late. Ive always had normal periods and now im getting concerned. any advice?
