Hi Tam12, welcome to BB

I go though Hollywood and they only put one back as well but I have a friend who went through Concept and they put back 2.

I had a HSG prior to starting IVF. Personally I found it a bit painful but both of my tubes are blocked so each time the Dr tried to push the dye through it was painful. As soon as he stopped trying to push the dye through the pressure stopped the feeling completely stopped so it is isn't like it is an ongoing pain. I assume if there were no troubles with blocked tubes the HSG wouldn't be a problem. Definately take some pain relief (I used nurofen) prior to HSG.
Anyone else with experience??

Good luck
