HSG with air bubbles and saline

Natalie
Hello! I had a heartbreaking ectopic pregnancy and ovarian cyst in March, so I took a break from Glow because it was too hard... I'm having an HSG procedure Thursday to see if there is damage from my surgery. My Dr. is doing the procedure in his office with saline and bubbles, rather than having to go to the hospital and have it done with x-ray machine and dye. Has anyone here had this done? Does it hurt? Just wondering how it goes...
