@jennythelib - Hopefully, now that you have adjusted to your new meds, your problem will be behind you. But there are actually some options for bacterial infection home treatment or alternative treatments that you might want to look into if it happens again.
One thing that works for some women is douching with betadine, which basically disinfects the vagina. (Yeah, usually douching is very, very bad, but this is a special case.)
Another option that has looked good in clinical research is a hydrogen peroxide wash. The hydrogen peroxide kills off the bad bacteria and actually creates a hospitable environment for the "good" microorganisms that your vagina needs to stay healthy.
As always, talk to your doctor before trying anything at home, especially if you're pregnant. BV can lead to serious problems (esp. for pregnant ladies) if it's not treated properly, so don't try to handle it without a doctor's advice.
