Vagina help

Ok so , a week ago I bathe in ACV 3 times in a row . The first I was a itchy , the second time it began to itch badly and I had NO discharge , the 3rd time it was burning a little bit so I drank some water that did nothing . So I began master-bating with some tissue and it got stuck so I got a little irritated down there so I tried to get most of the tissue out with a tweezer but it was still some stuck in there mixed with discharge in my vagina opening.So then I got my period & the itchiness good better but now today is my last day on it & I don’t have discharge like I usually do . I have been drinking cranberry juice and water a lot so I guessed that help but I’m going to have sex with my boyfriend this weekend and we are long distance so it’s going to be kinda special but I cant get wet . Any tips , I need help ASAP.
