I had a HSG last year. You lay down with your legs slightly raised (not the most ladylike position

), and they insert a dye into your tubes. I found it quite uncomfortable, but it was over very quickly. I went back to work afterwards because I felt fine, but about an hour later, I got severe cramps and had to go home and go to bed. I was fine the next day.
I have heard that some women have had hardly any discomfort when having it, so don't worry.
