How To Get Rid Of Vaginal Odor?

I'm 17 years old and a girl. I'm a virgin btw. And my vagina is smelling kinda fishy. I have a whitish discharge. It doesn't Hurt to go to the bathroom. But the smell I'm so self conscious about it. I'm more then sure it's bacterial vaginosis because I know it's very common. I've tried to treat myself with plain yoplait Greek yogurt. Please help me! I'm so self conscious about it. Can someone please help me. I've only been doing the yogurt for 1 day. It says I should do it for a week. I've had this for a year or so. But until now I've never done anything about it.
