Information of PCOS

So about 1 year or so I stop my birth control (Nuvaring) within the first month I gained 20 pound on. It made me very emotional and depressed. After I stopped my birth control I had very irregular periods. I went back to the gynecologist the other day and they were talking to me about pcos. I got tested for it and haven't gotten my results back. I'm super nervious. Does anyone have any good information for me? Ways to help me lose weight faster and easier. I have been trying and I get nothin.
