Blood coming from nipple?

Hey, mamas.

37 weeks here. Every now and then, I’ll squeeze my nipples to see the colostrum come out.

Today I squeezed. And along with 4 other dots of colostrum, a dot of blood comes out. All day, from that same spot, blood.

It isn’t from irritation, and it is not cracked. It does not hurt at all! It’s definitely coming from the inside.

Is this normal?
