Radiologist test ?? Dye in tubes...

Mercedes • Mommy to a 15 year old daughter , 12 year old son, 1 year old baby girl. - and pregnant with another girl
So this is all new to me .. I have to get a dye inserted into my tubes to see if the sperm is passing . any one else have this done ? Aslo If they were blocked what happens next? I'm so nervous I'll get bad news .... They told me I might not be getting pregnant after almost 2 years because of the scar tissue from my two previous c-sections.
