I had to chuckle at your post ""this is going to be a pinch" when they should say "now you're going to feel like your uterus is being gnawed on by rabid wolves" Believe me, I DO understand! After 3 miscarriages and then ALL the testing that followed and 6 months of fertility treatments, I've about had it all as far as cruel and unusual things done to you down there! I really can't figure out though what an SIS????? They do a test call a soniohystiogram where they inject saline or dye into your uterus, through your cervix with a cathiter and watch the solution on an ultrasound to make sure your tubes aren't blocked and to look for growths and other abnormalities. I had that one and it was uncomfortable, mostly pressure and some cramping but it was totally awful. The worse test I had as far as pain was the endiometrial biopsy. I screamed so loud they had to have hear me on the other side of the office building! I know the receptionist asked me if I was ok when I came out of the room because she heard me. I went home and went to bed for like 16 hours! They only do that one if they are checking for cancer or a luteal phase defect.
The best advice I can give you, is take some tylenol BEFORE you get there. Try to relax as much as possible. I know thats hard when your spread eagle in the stir ups but being tense will only make it hurt worse. If you are really nervous about it, call and see if they will give you a valium or xanax to take before you leave to help calm you down. Good luck and let us know how it goes!
