Hi,
You must talk to your doctor for more informations.
When I had a lap done five years ago the doctors faced with some problems that they didn't see on the ultra sounds and during the other examinations, so it can happen. I don't think that you did something during the recovery. But, to be sure about this problem you must talk to your doctor and do more examinations so you can know what's the problem, if there is any.
Hope everything will be ok!
Take care!
You need to ring your gp and ask why she mentioned endo?
have u been diagnosed with this before?
