I'm super worried

I was just in the shower and it looks like the inside of my vagina is peeling, like no how when you bite your lip a lot and it gets the white dead skin? It looks like that inside. So when I got out I got a mirror to see better and it's like that all inside and it comes off when I gently rub it. It doesn't hurt at all and I tried looking it up but not nothing other then it being an allergic reaction to the lube or condims I've been using. Could it be that? I already have an appointment at Planned Parenthood on Tuesday to be ur on birth control pills so I'll ask the doctor about it but I'm super worried rn about it. Anyone have any idea what it could be??????
