What probiotics at wal-mart or walgreens do i need to help with my bacterial vaginosis recurring?

Me

My medical doctor prescribed me some gel to insert up inside of me to treat my bacterial vaginosis and told me to take probiotics but didn't tell me which brand. Which brand is good? Do i take the probiotics during treatment or after treatment is over. I have to do that gel five nights at bedtime. What about those colon probiotics? Do they work on keeping bacterial vaginosis away?
