Hello, I had symptoms of UTI last week after getting Brazilian wax and intercourse. It burned when I peed, I had to go to the bathroom constantly, and one time there was blood though very little in my pee. The burning went away after three days, but now it s just itching down there. I also have back pain. Is this still a UTI or a yeast infection, or is it something more serious? I am 19 years old and I m afraid of a kidney infection. I don t have any vomiting issues though. Only constant itching and back pain. Thank you
