S.D.
I am surprised they want to remove it while you're pregnant! I'm not an expert or anything, but I have had ovarian cysts before, although I was not pregnant at the time. So, my advice might not help much, just wanted to share my experience with you. The few times I had a cyst, it was pretty painful, but I was told it should take care of itself in time, and they just kept an eye on it. It finally would rupture, and I would feel alot better. My doctors did not seem very concerned about it and explained that it is very common. My suggestion to you, is to get a second, or even third opinion before going through with the surgery. I would be concerned that undergoing surgery while pregnant might be more dangerous that waiting for the cyst to rupture.
