I think I have a UTI

I think I have a UTI. I had a vaginal exam done three days ago and my doctor said everything looked fine but I forgot to ask about some symptoms of UTIs that i’m experience (constant need to pee without going a lot, and slight pain occasionally). What are somethings I should do to help with UTIs. I’m going to wait for some results from my healthcare from tests they did during my visit.

Neither I (19) or my mom have ever had a UTI so we don’t really know things that could help to get rid of it. I read online to drink lots of water, cranberry juice, and foods with probiotics. Does anyone have suggestions on what to do until results come back from my doctors?
