so i had an endometrial biopsy

i had an endometrial biopsy like almost 2 years ago and im curious if they could have done something to damage me down there ...I get nasty cramps now for ovulation and periods also when i orgasming it tends to be just a hair painful like a .5 or 1 but it was never like that before ...and i did jump a bit during the procedure..."they didnt say it would hurt that much "

and as always google does not really help me answer my question....anyone else experience this or am i just crazy
