HELP!!! I have to get an HSG done....

Stacey • Angel baby 2/3/18 😇 rainbow baby born 12/18/20 🌈 and baby #2 due 11/8/22

And I’m freaking out about it. I’m so worried I’m going to be one of those people who have the horrible pain. I have endometriosis so I’m used to bad cramps but I hate pain. Also has anyone had any success with getting an HSG?? How long did it take you to conceive after??
