Mine did not hurt at all. I don't think I have a particularly high pain tolerance and I went into it expecting the worst. I would describe it as uncomfortable, but that was mostly because hey, hanging out with your lady bits out in a medical context is never very comfortable.
I have only had one, but from others who have done it multiple times, it sounds like experience level of the techs seem to be a factor in whether it hurts. I had mine at SG's surgical center where they do tons of them every day. Others who had them at places where techs do them less frequently reported that it was most painful. I've also heard that if your tubes are blocked, it is more painful, which makes sense when you consider what you are doing.
Good luck!
