UTI help?!

What can I do to prevent/ help the pain of a UTI? It seems like I get them once a month. I pee before and after sex, wipe front to back (never back to front), I’ve tried taking cranberry pills every day, I always drink plenty of water and I STILL get them full force pretty often. I even had one so bad at this time last year that I ended up in the hospital for 3 days (I was a day or two away from sepsis even though I had been on antibiotics). What can I do?! I’m tired of getting them so frequently
