hey hun, I found out I have a 6-7cm cyst on my right ovary that has been giving me problems/pains for about a year before i found out I am pregnant. I also found out my papsmear from right before I became pregnant was abnormal so it was alot to take in and alot to worry about. Well, I just had to have another papsmear (it's about 3/4 months later) so I'm waiting on those results, but my Dr. said that even though I'm getting pains from my cyst, that it should be ok since I'm not experiencing excrutiating pain. So I'd say that unless it's really causing you concern and you're doubling over in pain that it would be ok until after birth. Mine only hurts when I make very sudden moves like sitting up too quickly or bending over to quickly. Sorry if this isn't too helpful, but personally, I don't want to risk any procedures until after birth if its possible. (They wanted me to get a colposcopy and possibly laparoscopic surgery to remove the cyst, but that was prepregnancy).
I hope you feel better and that it doesn't cause you too much trouble!
