Nipple discharge?

Okay okay.

Weird question but I have these white dots on my nipple and when you squeeze them white stuff comes out? I’ve always had it even before getting pregnant, my nipple looked swollen with the stuff and I squeezed a lot out last week and I keep forgetting to ask my doctor. I previously had my nipples pierced before and it’s even coming out of my scar holes.

What is it Help 🤣
