Does anyone know what my vaginal discharges could be?

I am 14 years old and a virgin. Lately I have been have Vaginal Discharges that have been a clear-ish color and have a slight odor. I am very freaked out at what this could be because I am a virgin, so it can't be a STD. I haven't told anyone about it. Does anyone know what it could be, and what I should do?
