I had one last year and TBH it was pretty unpleasant, but shortlived. When they insert the dye I found it to be very painful - I was clenching the side of the bed pretty strongly - but the whole thing lasted maybe 5 minutes and then she was out of there. I was told by the clinic to have it done after AF but before ovulation - they booked the test after my initial bloods on CD1. I still had a bit of discharge when I went, so it must have been about CD 4 or 5.

Can't remember costs exactly but it was about $200 for the ultrasound place (and got $80 back from Medicare I think). Then there was another $160 odd charge from the fertility clinic for the doctor they sent to perform the test.
