so as gross as this might be to say, i have a yeast infection/bacterial vaginosis, and im thinking the best option to cure it is by using acidophilus cream/pills (is this a good idea?), if so, which brand/type (cream/pill and brand) would you suggest? and where can i get it?

I completed my regimen of 500mg flagyl, 2 pills a day for 7 days to treat BV yesterday, and was wondering how long I have to wait before I have sex. The pamphlet I received did not specify. I know obviously I was not supposed to have sex while on the pills, which I didn’t, but am wondering if everything seems to have cleared, when I am safe to have sex again? Thanks!
