I got pregnant after my hsg. I can say it was uncomfortable, not painful, but then, I seem to have a pretty high pain threshold and did not have any prior tubal issues. I had also been successfully pregnant previously, so entry through the cervix may have been easier. I had mine done at WRA b/c I couldn't get in with the RE. The pregnancy didn't stick, but heck, at least I got pregnant at almost 43. Now I am 43 and still trying.
