Anybody can get a cyst. There very common, I have them. I am lucky because they don't bother me. Who knows it could be gas! The only way to know is if it keeps bugging her, she needs to see a doctor. Good luck
she also says it doesnt run in her family we are both very confused...
but this has only happened this last time we had intercourse. would that narrow something down?? she thinks its to do with her ovaries...
It could be so many different things or maybe just nothing? Pain on the right side could be appendix, a cyst or tubal pregnancy. There is no way to know without a doctor. She should make an appointment to see her ob/gyn soon.
