I had a yeast infection about a week ago, and I did a Monistat. The symptoms went away and I thought I was good. I started having vaginal itching about 2 days ago again, so I grabbed a 7 days Xtra strength monistat this time. And am on the third day with only a little relief. My discharge started out as white and chunky like a yeast infection and now it's yellowish. Does this sound like Bacterial Vaginosis?
