i had it done as part of recurrent m/c testing. My outcome was that there were no issues there with my tubes which was great
I took 2 panadol (I think you can take panadeine.. but im allergic to codiene - but obviously best to check with your care provider) and 2 nurofen an hour before the procedure to help with pain from cramping. I was lucky and didn't have any but they told me that most women get some cramping during and after the procedure. I had a bit after, but nothing bad.
Very best of luck with it! I wish you all the best!
