For the past month (after 6 months of pumping) at least once a week (pumping 4x a day) I've gotten bloody milk on the left side. Usually it was after 20+ minutes pumping, but yesterday happened at 18 and its usually small thin 'clots' of blood. (clots may not be the right word as its not coagulated, but comes out in a 'spot' of blood).
It doesn't hurt, I don't even notice unless I look down at my milk. I don't believe its from my nipples either as they are not cracked/sore.
From google and reading past posts its nothing I need to be worried about, but any other momma's dealing with this? Any info to share? What is the cause?
