HSG Test today

So I had my HSG Test today. Read up on it all beforehand, took pain killers as advised before it too. Jesus! Soooooo painful!!! I was in agony when they inflated the tube, they had to stop for a moment, reposition and go further. More agony, trying to belly breathe but had to hold my breath it was so sore. My tubes appear clear, no blockages, which is good but equally confusing as to why we're having difficulty trying to conceive. However I'm still experiencing quite a lot of discomfort 8 hrs later, felt nauseous about an hour afterwards with stabbing pains. Not at all what I expected when researching it. Anyone else had any problems?
