For the past week or so I've noticed that my vaginal discharge has been very different from what it regularly is. It has a very strong, kind of bad smell. I wish there was a better way to describe the smell than " bad" but I can't think of anything I could compare it to. Another huge change is the taste. It tastes.. spicy. Like tongue tingling spicy, which strikes me as a bit strange. It also tastes sour. So, with all of that I was thinking maybe I had BV, but there's absolutely no fishy smell and no change in the consistency of my discharge. It's only the smell and taste that are off. I haven't eaten anything spicy or out of the ordinary for my regular diet (no meat or gluten and limited dairy). I did have oral sex performed on me a few weeks ago, which I'm almost positive must have something to do with this change. So my main question is... does this sound like BV? An STI? Some other kind of imbalance? As a side note, I'm due to get my period any second now, so if this is some kind of imbalance, is it likely that my period will clean everything out and rebalance me?
