UTI 😭

Ka
So I went to the hospital today for lower abdominal pain and throwing up. Turns out I have. UTI, all they did was give me a antibiotic and nausea medicine and told me to drink plenty of fluids. Any other recommendations I can get from you ladies. I've suffered from a UTI about one a month since I was 14. I'm a clean person. I have no clue what's wrong with me. Could it be where I was using vaginal wash?
