So I've noticed some clear (sometimes faintly whiteish) discharge out of my nipples when I give them light pressure or sometimes when I don't. It's not a lot at all and I'm not pregnant like at all I am actually on my period right now. I'm worried it couldn't be something concerning but my breast don't hurt and there are no other signs of anything being wrong :/ im 18, almost 19 and yes I am sexually active could this be something minor or worry worthy?
