What is wrong with my vagina

Idk what's going on down there! I had a uti a few weeks ago when I was on vacation , I was put on antibiotics for two days and it went away. 8 days ago when I came back my BF fingered me. Than a few days later I started feeling uncomfortable down there. It was like a burning and itchy sensation I thought it was getting better until just a few minutes ago I was walking and my vagina just got real itchy/pain and discomfort I went back home and used the bathroom and it burned when I went pee when I wiped I notice like regular white discharge and than a tiny bit of brown discharge with in it! I haven't had sex, idk what wrong with me ! It feels real uncomfortable down there.....
