Ok so I am on my second mirena iud, this one has been in for about 2 years. I haven't had any problems with the iud ever, until last night. It was very weird everything was going like it should very nice and pleasing. Until I decided to I guess take the lead and get on top. About 30 seconds into it it felt as if I was being stabbed with a piece of wire in the uterus. It was horrible and ruined the whole thing. Have any other women had this problem, does this warrant a trip to the gyno? Any info would be greatly appreciated.
