Whether you are having pain or a period....cervical cancer does not distinguish between women who want or don't want children. And any change in menstrual cycles is cause for concern. Period. (no pun intended lol).

I had PCOS. It was directly related to weight gain. At one point I went in to have a hysterosonogram (look it up, it's painful) and there were over a dozen cysts on each ovary and a polyp IN my uterine lining. I lost about 35 lbs over a summer (intense field work in heat) and my symptoms essentially disappeared. My body was completely out of whack. Although I was drinking heavier and smoking which I'm sure didn't help. I was also working 40+ hours a week while going to school full time and I know stress doesn't exactly help.

So that's what went on with mine. But everyone is different. Yours could be completely different. It's pretty complicated how every hormone works together (or doesn't) and birth control was a big part of mine. I had to go on the lowest dosage of progesterone and estrogen which seemed to help.

I hope you get your stuff figured out. Being a chick is a hassle sometimes :-/
But it has its perks too lol
