I was quite alarmed this morning when I started pumping and saw the first part of my milk from my right breast had a stream of blood in it. I do have a milk blister on that side but I haven't seen blood in the milk before. Does that mean my daughter is ingesting my blood as well? I continued pumping and it was just those first few pumps that had milk in them. I was able to get 4 ounces - I'm assuming this milk should be thrown out, right? And should I assume it is the milk blister or be concerned it is something else?
