Dr.visit (worried)

So i just got out of the dr .wanted to check my ovaries and all of that,,everythings fine..but since i had an ectopic pregnancy back in feb..he wants to send me to the hospital for a hystosalpingogram..which meannns, they will fill up my uterus with ink..and if that ink comes out through my tube means its ok and i can get pregnant.but if no ink comes outt,means my tube is blocked..i dnt have a left tube.only my right....has anyone gone through this ? And was able to get pregnant ? Please answer,im really worried and sad that im not gonna be able to have babys :(
