Recently diagnosed with PCOS, I’ve been doing all my research on what I need to know about the syndrome. I have been put on Metformin and have been taking it religiously every day. I was 17 days late for my period which lasted 5 days and was SO heavy. I just ended 2 days ago and I am still cramping so bad! I’m discharging so bad also and am clueless as to why it’s like this! Any ideas?
