Post-HSG pain & headache

Hi!
I had an HSG (hysterosalpingogram) done last Tuesday and since then, I've been feeling really 'off'. I was super-sore for a few days after the procedure (it was the worst pain, by far, that I've ever experienced). I've been nauseous and exhausted since then...and I've had an on-again off-again headache.
I saw a doctor at a clinic, and he figured it was just physical trauma from the test.
I'm, going to try to see my doctor this week, but until then - has anyone else had this experience? Just feeling really rough for almost a week after the procedure?

Any answers would be awesome!

Thanks!
