I just turned 20. My mother has PCOS, and in March 2006 I had severe abdominal pains, and discovered an ovarian cyst the size of a tennis ball. I was just 18 at the time. Passed from doctor to doctor, a exploratory laparoscopy was scheduled immediately, and then the specialist decided two days later that it was "not necessary" that there was "probably nothing to worry about". I was told when the cyst was first discovered that it would shrink, burst or otherwise fade away into nothingness and not matter at all. All it has done is increase in size. So, here I am with my OCP prescription and an occassional ultrasound to monitor my constant companion - my cyst. The pains come and go, and things have been good for a while, and last week I had a normal period, and 4 days after it finished, I had breakthrough bleeding (which I have never had). That bleeding has developed into another fullblown period - literally. The bleeding is very heavy and full of clots, and I'm quite scared. Has anyone experienced this before? Is this a common complaint? I was anaemic to begin with, and I'm concerned about my current rate of blood loss. Am I validated in this concern, or am I simply overreacting?
