Vaginal ph off or something

Hey guys so I went on birth control about a year ago and got off of it in October but ever since I’ve used it my vagina has been acting all sorts of weird such as itching, smelling, excess discharge (sometimes thick, sometimes watery) to the point where I have to use boric acid at least once a week to feel normal down there. When I first went to my gyn about it they told me I had a yeast infection so they put me on the vaginal yeast prescription then they told me I had Bv and I was on antibiotics but nothing changed since I took any of those I don’t have any sti/std cause I definitely tested for that but idk what’s going on or how to fix it. I don’t wanna take boric acid for the rest of my life. Does anybody have any advice to help me get down there back to normal for good.
