Nervous about hsg

Tomorrow morning I’m having an hsg test done to check for any blockages, I have had one ectopic pregnancy before so I know that there is a chance of one of my tubes being blocked, but does that mean it is definitely blocked? I have also had a pregnancy that resulted in miscarriage, but I do know that the pregnancy was in the uterus so I feel that at least one tube is okay.

Also I’m basically terrified bc when you look online there are horror stories of how excruciating the pain can be😒

Any experiences or advice is appreciated!
