So if you are on the fence just do it. I just did mine 30 min ago. I am completely normal with no blockages and a normal uterus. So I feel much better about myself now. The worst part was when he inflated the balloon in my cervix. Maybe 2 min of hard cramps then I didn't feel the dye at all. It was kinda cool seeing the X-ray of my insides. I have had 2 IUDs the mirena and Skyla and those hurt way worse and the cramps lasted days. I had mild cramps for 20 or so min and now nothing. So it you are afraid don't be it's not that bad.
