Weird smell / acv

So i read that apple cider vinegar can be used on your vagina. So i used it a few times on like the outside where i have razor bumps/scars to see what I'd do. Literally used it 3 times or less, and ever since, my vagina has this weird smell. Im not sure if every one else smells it but you know how your own vagina smells. It smells kind of pissy. And its been like a month since i used the apple cider vinegar. So what can i do to make the funny smell go away? I have some feminine spray that i used to use. Should i try that?
