Bladder infection/UTI

Hi,

So, I noticed two days ago that I probably have a bladder infection because I’ve had one before two years ago. I noticed it because of the burning sensation after I peed and blood in my pee. I took a probiotic right away that night. I bought cranberry juice and vitamin C supplements and drank like 3 glasses of cranberry juice and took a supplement and a probiotic. My symptoms are definitely not as bad as my last UTI. In the first half of the day there isn’t any blood and the burning is barely there. I also don’t really have the urge to pee. How long will it take to go away while I continue drinking cranberry juice, water, and taking probiotics and vitamin C? Because I cannot afford to go get tested and buy antibiotics. Also, because it’s snowing and I can’t go anywhere lol.

Thank you!
