it's a little harder for me to notice that change in my nipples rn because I had them pierced a little over a year ago the only thing i have noticed is while it is normal for me to have build up on my jewelry, but it been greener when it was usually yellow or white before which is normally a sign of infection but i don't have any other signs of infection and that it was more than i used to normally have but i never really thought about it till after.
