I just had this done in October. My doctor suspected I had endometriosis, but actually went in to unblock my right tube. I ended up having a lot more endometriosis than he'd suspected (although I'm not sure which stage it was). The majority of it was in my right ovary and I also had beginning stages on my left side. He went in thru a tiny incision just above my pubic hair, one in my belly button, and because I had it on both sides he had to make tiny incisions on both the right and left side of my abdomen. The surgery was quick, but my recovery was a little longer because I reacted to the anesthesia - I was there and home in one day though. The doctor will/should tell you to sleep and sit while elevated so the CO2 can leave your system. Moving around is different for everyone - I was in bed for a couple days, but that's mainly because he tied my right ovary to my side so it was uncomfortable to move around (once he let it loose it was SO much easier). Many women can move around much sooner.
My doctor isn't putting me on birth control, but that's because I had this surgery so we can try for another baby. Just FYI, if you do have it in an ovary and they remove it, the first menstruation is painful - at least it was for me. The first day I could hardly move because of the pain. The pain pills the dr. gave me wouldn't even really help, but ibuprofen did. That's just what it was like for me.
Overall it really was a quick and easy procedure. Everyone's different though. I wish you luck and a quick recovery!
