Just wanted to share my experience today of a hsg test. I was v nervous after reading some horror stories online and whilst it wasn't the nicest thing to do it wasn't nearly as bad as I thought it would be. The first part when the speculum went in wasn't nice but no different to a smear test. The tube going in was fine it was when the dye started to go in that I started to feel cramps. As someone who doesn't have painful periods the feeling was a bit strange and got worse probably for a couple of mins. Made me want to squirm about and hold my tummy but couldn't as the x Ray machine was virtually on top of me. But it didn't last long in the grand scheme of things. Have had quite a lot of leakage and some minor cramps over the course of the day but generally felt ok. They couldn't give me the results there and then so got to wait for consultant appointment in a couple of months.
Hope this sets some people's mind at ease. It's not the most comfortable thing in the world but it was bearable for me and if it works then it will all be worth it!
