I think you have to be several months pregnant before that starts to happen, so she's probably not pregnant.
I knew that. Im not worried about the pregnancy so much. Im curious as to what else could cause this to happen.
some women, depending on what they wear, lactate for no reason. does she wear a bra everyday? or no bra at all? if she is not wearing a bra the exposure to her shirt or whatever clothing can over-excite the nipples and in fact will activate the glands and the breast will produce milk, any over-stimulation will have this effect, usually over an extended period of time, if the discharge looks abnormaly thick or off color def. consult a doctor. my mother went through this and we thought she had cancer but turns out she just needed to wear a bra everyday.
