Help me UTI for 2 months now

Okay so I have bad UTI I have been to the doctor last month and they prescribed meds but I don't have any insurance and I couldn't afford the medication! I feel so helpless I don't know what to do 😭😭😭😭😭 I have tried garlic, 3 cloves 3 times a day and I thought I was getting better but then I started my period and now it seems to be getting worse I bought the cheap UTI test strips and I still have the infection. 😭 I have cut all sodas out and everything I just feel stuck bc I really can't afford the antibiotic.
