I was diagnosed with Pcos after my first baby. I know that sounds bizarre and over a 17 year period I had 4 children. Although I've always had irregular periods, excess hair and been obese I've never been on metformin. However now in my mid 40's I'm morbidly obese and my dr has suggested I consider it for weight loss but he's asked me to do some research first. Any help appreciated. Thank you in advance.
