A few years ago I began having my menstrual cycle I had it for 6 months straight lost over 50+ pounds and doctors never knew what was wrong. I used Yaz, Yazmin, Ocella, & a lot more birth controls trying to stop the bleeding it finally stopped and I went back to having semi-normal periods. For the last two years I ve had little to no periods at all, low sex drive, moody. I have been trying to get pregnant and obviously nothing is working. Please can anyone tell me what could be going on
