I have about 5 ovarian cysts, 3 on my left ovary that are a few cm and a big one on my left ovary thats 5 inches and then another small one. I am having surgery to have the cyst drained or removed Thursday and to remove some endometriosis. But my breast hurt so bad, it just started yesterday. My nipples are killing me just like they did with my last pregnancy and now my breasts just feel full and hurt really bad. Could this be caused from the cysts? I'm kind of worried I may be pregnant but really early, I'm only 10dpo. I had a negative blood hcg on Friday but I was only 5 dpo then.
