IB or help?

So I am est. 10 dpo. I am a few days into antibiotics for BV. And today I see this. Only been going on for 12 hours and this is the most their was when I wiped. It lines up with IB. But Im not sure if thats what it is or if my body is "cleaning" from the antibiotics. I have never had BV or taken this kind of antibiotics before. Any suggestions...
