A year ago, my period was two weeks late. I was getting worried because I was getting no period symptoms at all. All of a sudden, my period came. It was horrible. It was super, super heavy. The cramps were terrible. I've never in my life felt cramps like that. They hurt so bad, I couldn't stay still. I was in tears. The pain was almost unbearable. I check my pad and there was of course uterus lining, but also two very tiny circular pinkish-white things as well. What were they? Cysts?
