Ok, I’ve never had an IUD but last year I needed an intrauterine biopsy, which meant the nurse needed to insert an instrument through my cervix. I literally screamed and she couldn’t complete it. She then derided me. “Haven’t you given birth?” I said yes, that I’d pushed out a baby more than nine pounds and did not scream while doing it because that hurt less than what she’d just done to me! (I can prove it. I have that birth on tape!)
She acted like I was being a baby but it was tremendously painful.
