Constant UTIs...

So I’ve had constant UTIs for the past month and I drink 3-5 of my water bottle which holds 40oz a day....plus 2 glasses of cranberry juice (100%) a day and I feel it’s gettin worse....I’ve already been on antibiotics and within 3 days of being off of them I developed another uti...I know for sure it’s not an std or anything....are there any other things I could try at home for them?? I’m calling my doctor on Monday, my doctor isn’t in the office on Fridays.
