Have been sitting at my desk all morning with really achy boobs, my right one in particular. Went to the loo to take my bra off for a while, and my right boob leaks a colostrom-like substance when squeezed. It looks awfully like when I breastfed DD, but a pregnancy test a few days ago said negative. Is there any reason for boobs to leak apart from pregnancy? I don't want to get my hopes up as have been trying to conceive, but am freaked. Any experiences/insights? I'm trying to stay away from google as it always makes things worse!
