So I think it was m April period that I went to the hospital for UNBELIEVABLE pain and found out I had a cyst rupture. My periods now are kinda lighter than they used to be, could the cyst cause that? I am sexually active but we use condoms and pull out together every time. I know I’m not pregnant because I’m on my period now and the blood is bright red like normal. Is it normal to become a little lighter? Could the cyst have anything to do with it?
