BV?? HELPPPPPP

Hell

So I’ve suffered from bv for the back 6 months and i haven’t went to the doctor about it because of my parents. They won’t let me. They think I’ve had sex which I’ve had but they can’t know that bc they are really strict. I’ve tried doing baths with the vinegar but it never worked. It got less bad where it only happened when i had sex but now you can smell it on me so i bought a douche and i put half water half vinegar and i douched with it. When should i do it again and how long till it’s gone ?
