Need some advice! I am getting an HSG done next Wednesday. My Dr. said it was "crampy" but most people returned to work following the procedure. I googled it (dumb!) and read horror stories and am now freaking out!

DH is traveling for work next week so he can't be there for emotional support, but my Mom is insisting on coming. I feel like a child to have my mom come, but at the same time want her there in case I get bad news! (She lives 3hrs away).
Thoughts for those who have had it done? Should I just go solo? What was the pain 1-10?
