Infection in urine

I just been to see my gp and he done a urine strip to check for infection, he told me it came back that I have an infection in my urine but no protein, in my gp office its very small and he wasn’t exactly able to tell me what kind of infection it was, what are the types of urine infections you can get? It hurts to go pee and I’m going a lot more than usual, he put me on anti biotics for a week ?
