Bacterial infection/probiotics

T

I have had 3 bacterial infections within the last 2 years, never had one before that. Went to the doc the other day and have it again, the last time was over a year ago. I wear cotton undies, stay dry, clean with mild soap/water, stopped using tampons and a few others things. She said there isn't much else to do other than what I'm already doing and that the bacteria just gets thrown off sometimes. She prescribed the pills, twice a day for a week but if this doesn't work she's gonna put me on a 6 week regimen. I've been doing a bit of research because this is driving me crazy and some people highly recommend probiotics. Does anyone here take them and can recommend a type/brand or whatever? I saw they have some exclusively for women but I'd prefer real life suggestions to a 2 year old article!

Thanks!
