Hi, I m 17 years old and I m not sexually active so there is no chance I m pregnant, but it looks like skin around my nipple is pealing away and broken, and there s a yellow whiteish plug looking thing inside my nipple, i don t know if this is normal or not because I don t really look at my nipples a lot so I don t know if they normally do this or if I need to be concerned about it, please get back to me!
