Need second opinions

I’m very nervous have a doctors appointment tomorrow but I had done oral sex about 2 months ago and I had a normal period during that week I could not shower from a camping trip after my period I started feeling soreness in my vagina Vaseline would make it itch so I put cream on it then it was good but now every once and a while I still have slight pain in my stomach or redness and pain like dry raw feeling in my vagina no unusual smell or discharge though what are all the possibilities this could be bacteria ? sometimes it’s a slight burn or itch but not really and whenever I look down there it’s milky white discharge like watery and the redness is not really there so Idk? My diet hasn’t been the best and I might be dehydrated but I’m worried !
