I am super sick with UTI

Last Sunday I got up and super nauseous. I had to teach so left home but I drove 30 seconds and came back home. I started to throw up 4 times. It was like morning sickness but three times horrible. I only threw up one time at night during the night. This feeling like I have a flu and super nauseous. Anyway. Next morning (Monday) ended up going to an ER (pay1300 dollars). They said I had UTI. Monday afternoon came home and next Tuesday both two days. I bed rest. Alone. No one was right next to me. Today is Wednesday. I am feeling better. Keep taking antibiotics for five days. Is it common to have this? I don’t know. I did not even feel when I was peeing. I thought I had a food poising. The worst part was nauseous. Seriously. Today is better. Though.
