Yogurt and Acidophilis pills for the vagina?

I'm on antibiotics for a BV infection that started a week ago. Since ive heard it reoccurs alot because of the antibiotics so i decided to try the whole yogurt in the vagina trick(yes i bought the right kind) this is my first night of trying it. I also bought Probiotic Acidiphollis chewable vitamins to start taking daily. Im wondering if it will work? And if it will, will it make my vagina taste and smell good? because thats what ive heard
