So I am going to my dr tomorrow for a saline sono they thought they found a polyp in my uterus. I am scared because when they were going to do the HSG test but realized it was too much of a risk since I am deathly allergic to iodine. I am so nervous that the saline solution will hurt me. Will they clean me with anything with iodine I am so so nervous! I am so nervous please help! I am deathly allergic to iodine and all iodine based antiseptics
