White smelly discharge no itch or burn ! Please help?

So for about a month I've had white/yellow discharge. A yeast infection has itching and/or burning but I don't have that just the discharge. hen I read the description of the discharge from a yeast infection it is just like what I have? I don't know what it is. Has anyone experienced this before? hat happened, should I make an appointment with my doctor? Im 17. Please Help
