Cat scan while pregnant??

So I am 10 weeks and 4 days

I came to the hospital for some cramping and painful urination

I have been taking azo so I was just hoping maybe they could test me for UTI

well they dont even take me to labor and delivery and then after waiting almost 2 hours they throw me in a room and tell me they gonna give me a cat scan and to get undressed

I freaked out!!! A cat scan?!?! I'm pregnant!!

U not suppose to have any sort of xray or radiation while pregnant are you???

I freaking left and idk why doctors and hospitals are always so rude to me
