I Am A 17 Year Old That Is Not Sexually

I am a 17 year old that is not sexually active. For a while now I have had a very strong smell coming from my vagina, it is definitely not the regular kind of smell. At first I thought it may be a yeast infection, but now I'm certain it isn't. My discharge also seems to be not normal, it doesn't really exit my vagina. It also isn't clear or slightly white, it's very white. What kind of infection could this be?
