Birth Control
"I  have PCOS and worked for years on diet and exercise to regulate my period. But never was able to get to regular to where I could predict it. For about nine months prior I was taking metformin to help and I lost about 16 pounds with it. So My gyn recommended taking birth control to help regulate my cycle.  My period became regular to between 22-24 day cycle.  However I had intense bloating and crazy food cravings, that I have never had before.  My mood swings changed to the point where some months I would be really depressed and down.  Around the 3 or 4 month of being on the pill I started having severe break through bleeding that lasted between cycles and eventually did go away. Once that stopped I was experiencing severe indigestion."
