WHAT'S THE MATTER WITH MY KITTEN? :'(?

She will sometimes walk around wobbling with her tail all the way up like something's hurting her by her . I looked at her and it looks like it's bleeding...Well, I know it's bleeding because it's sort of looks like it's clotted on the rim of her . It looks like something pink is coming out?djhgdfgfh I'm really worried :'(
