Probiotic vaginal suppositories for bv??

I found something in amazon. That is said to prevent bv, and yeast infections after taking antibiotics. I am staring flagyl. I plan on taking j. dophilus, and  using the insert.  Have you tried probiotic suspositories for bv? What's your experience? 

Probiotics didn't work for me

Really? What probiotics have you used?

Rephresh, femFlora, regular acidophilus, vh essentials. There are a few more but I can't think of the names. None of the home remedies worked for me long term
