Will I get a yeast infection now for taking that unnecessary treatment? (Only 1 pill). I took it 7 months ago for the same reason and it was BV then too. I don't know why she keeps mistaking the two. But did that unnecessary treatment 7 months ago cause it this time? She just swabbed by vagina, she said it looks like yeast in there but I didn't see her look under a microscope :(
