Bv or is this normal?

Rebecca

So i have had bv in the past. I’m not sure if this is just my pee or if this is yellowish discharge. I do have a slight sour-ish smell and it kinda smells like i have been sweating down there but I haven’t. So I am just concerned that I am having a bv flare up…especially bc i know you aren’t supposed to have sex while having it…and me and my fiance are trying to conceive…please help!
