I don't see blood in my milk but, I do on my nipple. It started out as a white spot on my nipple. I thought I may have a block duct so I followed the instruction for that (nurse, nurse,nurse, and offer that breast first at feedings, and pumping afterwards). Now the white spot is gone but there is like a whole in my nipple. my son's bm have been darker in color and with some little back dots in them. And just this morning he had the same color brown come out with some of his spit after nursing. It hurts real bad when he nurses off it and pumping it. So I hand expressed the milk out after his last feeding. I plan on calling my doc thismorning,too. What should I do?
