HSG this morning - now feeling unwell - should I be worried?

Rebecca

I had a HSG done this morning at 9am, it’s now 9pm and for the last few hours I have felt sickly, achy, chills like I have a fever and a sore throat. I am wondering if these could be connected and if I should be worried or is it just a coincidence? My doctor didn’t give me any advice on what to do afterwards if I felt unwell.

Help please!
