I have a darker skin tone on my vagina than the rest of my body and I heard that thats normal but most recently my vagina started to have a particular spot on the vulva where it began to peel and now it is a pinkish colour. I thought nothing of it until after 3 or 4 weeks it was still there. Now I have a patch of pink on my vaginal lips. Can someone please tell me if this is normal or if I should be worried?
