Go back for a re-check after a month and see what's what. If in pain, go sooner. I would think your Doc is on track, that missing the BCP could easily have caused the issues. If you ruptured a cyst, you will have free-fluid. What matters is does the fluid resolve or get worse? Do the cysts resolve or start to get smaller? Only re-testing can answer those questions.

Oh and I forgot to add that there is free fluid in my pevis and my stomach is swollen. Is that something to be concerned with or will it just go away on its own? My CA125 came back normal.
