Hi Sarah,
I had heard many horror stories about HSG's, so by the time i went and had mine, i was filled with dread! However, all that washed away and I was left feeling afterwards, well what was all the fuss about!!!
It is just like having a smear - assuming you've had one of those?, as in they use a speculum. They then insert a fine tube, squirt the dye in, take a few x ray pictures and that's it - more or less! The discomfort may come from the dye "filling and spilling" from the tubes. At worst you may get some mild cramping. You should get to see it all happening on a TV screen nearby - fascinating!
Don't think I bled that much. Used a pad, as advised against a tampon, to cut down risk of infection.
You will obviously get some leakage from excess dye - which will come our clear - it just looks blue on the x-ray pics!
Some may not react well to the procedure, but in general, it's pretty harmless and does generally tell you there and then whether or not your tubes are blocked!
Very best of Luck and let us know how it goes!
