ovarian cysts are caused generally by the egg not releasing from the ovary. It clings to the end and absorbs and fills with fluid. When it bursts, I find that I too have a lot of sharp pain. (went to the er and had the most horrific internal ultrasound of my life) I find that after the cyst has burst I am wiping brown discharge but nothing enough to wear any form of protection. I have had fleshy/bloody clots pass in the shower and toilet and they are usually the size of pocket change. It may not be the answer you are looking for but know that you are not alone. Good luck and do lots of research. Keep us all updated on how you are doing.
