Pregnancy or UTI?

I had sex with a condom a about 2 weeks ago and it didn’t rip. But I’ve been feeling gross since. The first week I had really bad aches in my lower abdomen and lower back. I have been bloated for the time being. My urine is also foggy. The second week my back and abdominal pain went away but i started to experience nausea without vomiting. my breasts are a little tender but that could just be all in my head. I pee more often but I’m also drinking lots of water every day. My period is expected to start in a week. I have extreme anxiety right now, I’m 17, and really don’t want to be pregnant.
