Omg!!! I burnt my vagina TMi

So i think i have been having BV symptoms and my skin felt very tight on my taint to the point it was painful. I also have been having discharge with an order so I figured i was out of tea tree oil so i put some peppermint oil down there. It felt too tingly but i was omw to work so I couldn’t wash it off. All day it felt somewhat uncomfortable but when i got home it was really bad and then me and my bf had sex and its worse. It looks irritated and almost burned. My lips are dry but swollen and but my vagina is like leaking. I think it’s trying to heal itself. Wtf did i do? How long does this kind of irritation take to heal.
