No, taking probiotics for the stomach would simply be because you've been on a lot of antibiotics. I got a vicious stomach thing that took hold really well, last time I had a run of strong antibiotics, because there was nothing protective in my stomach to prevent it.
The vaginal flora would improve if you douche with a live-culture plain yogurt. Or you can just let it get better over time, IF you don't get BV again and have to go back onto antibiotics.
Being on birth control would not prevent a boyfriend from giving you BV, if that is what is happening. But it would prevent you using Plan B as (in essence) a regular form of birth control. It's just not meant to be used that way; it's too hard on your body.
I'd talk to the doctor and see if he thinks your boyfriend and you should have the next round of antibiotics at the same time.
Would getting on birth control help to get everything back to normal?
Thanks for your reply. Would probiotics for the stomach still help my vaginal balance? Also, I have not had sex in a few months.
OK, that's a lot of Plan B. Why don't you just get on the pill, or use condoms? It's really not supposed to be used that much, and maybe it is enough to upset your system and make you more susceptible to gardnerella.
It sounds like you are having unprotected sex. A man can carry the bacteria and pass it to his partner, or at least my doctor had my husband and I both take Flagyl at the same time once when I had BV, for that stated reason. He didn't want us to pass it back and forth, making the antibiotics run I was on useless.
My thought is that you need to get your vaginal flora back in order after so many runs of antibiotics. I'd take a probiotic for my stomach, and maybe even consider (after your next run of antibiotics is over and you are clear of BV) douching a few times with a live-culture plain yogurt.
But consider, it is possible your guy is giving this to you. Condoms are your friend.
