Uti back to back

Had a uti about a month ago.. needed to have an IV for a week because the meds for that specific uti are not safe so the one I could take was only IV administered. Doctors office didn’t tests after my meds ended to see if it cleared up. Well now I saw my test results online and I have a UTI yet again!!!! I do NOT wanna do the IV again it was horrible and the medicine made me so sick!!!!! Any advice on anything to take other than water and cranberry juice to help clear it up
