Okay once again, maybe tmi! But my right nipple has been hurting for 2 days. The weird part is that it's only my right nipple, my left doesn't hurt at all. And it only hurts when it's touched or squeezed. So basically any contact with my nipple hurts. What could this be ? My calendar says I'm a day late for my period . Could this be pregnancy, my period, or an underlying cause ?? It's worrying me because it's only in one nipple! Please anybody who can relate or give good advice will help! Any negative comments please keep to yourself !
