I had an ob appt and mentioned it so she had a look, it was just colostrum that had leaked and gone hard, she said she's not sure why it went so dark, but that its not unheard of, some women are either like that, or its from bra/cloth breast pad dye. She said just to continue to put the lansinoh on, and it has all gone now, as well as the pain and theyve repaired using the lansinoh too, where it was peeling off it was taking skin with it was why the crack and the little bits out of my nipples. i was very relieved to hear that, and even more relieved that they repaired so quickly. thanks for thinking of me hun.
