At home remedies for UTI?

I’ve gone to my doctor twice now for the same uti infection and nothing that he has prescribed has helped me. My boyfriend and I are at our wits end. We’ve discontinued our sex life, I’ve probably drank two galleons of cranberry juice, I drink 10+ glasses of water a day to the the extent that my urine is now clear all the time, I’ve taken OTC remedies and nothing has helped! Does anyone out there have the cure for my ailment?
