Okay so over the past year I've noticed Greg dots inside my bra where my nipples go. I am 19, not on birth control of any kind, and have never had children. I don't notice any type of secretions, or an abnormal amount of sweat from my breasts. I really don't know what this is, and am slightly concerned. It seems to be worse when I'm under more stress. I don't smoke, and I rarely ever drink, and I don't do any medication or drugs. Tell me what you guys think, I'd appreciate the feedback! (I'm going to the doctors one my insurance is set up.)
