My pcos is very severe. I haven't had a period on my own in 3 years. Last period I had was in November because doctor prescribed me provera. I have done everything (metformin, vitex) for 2 years and nothing. I stopped a few months ago all my medication and stopped trying.  I have been working a lot lately (I'm a server) so I have been doing a lot of physical activity and I'm so so excited to say I had my period this week !!! A full 7 days and on my own. I'm so excited and can't wait to see if I get my period next month.
