I have PCOS too. I was diagnosed when I was 16 and put on the pill and Metformin almost immediately when they found my blood insulin levels were high and that I had big cysts on my ovaries.
Now, with my recent IIH diagnosis, I have been taken off the pill 11 years after starting it. I'm kinda worried about what is going to happen, because I only ever had a couple of periods naturally off the pill (I was a late starter) before I was diagnosed with the PCOS, and now that I'm completely off the pill I'm not sure what my body is going to do. I am having a lot of pelvic pain at the moment, and I am overdue for a period but it hasn't arrived yet. I'm really hoping body hair and acne doesn't flare up, though I have had some killer zits over the last couple of weeks so it's not looking good.
I am trying to remain positive, but it has me concerned. Hopefully my ongoing weight loss for IIH will assist with the PCOS too.
