UTI😢😢😢

I just got a pretty bad UTI while at work. I’ve taken 3 ibuprofen, 2 cranberry pills, and my bf brought one pill I had left over from last time. However, I’m bleeding worse than I ever have. And I am cramping! Could it possibly be a miscarriage? I don’t know if I’m pregnant or not but this hurts SO BAD and I’ve never bled THIS bad with a UTI. I can’t go to the doctor because I don’t have insurance or the money. What is a fast remedy to make this go away! I am so uncomfortable and don’t get off for another hour and a half 😕
