Re: crusty nipples
A little clear, white or brown discharge from nipples is not unusual, even in women who've never been pregnant. The fact that it's happening on both sides is also a sign it's probably normal.
Nipples leaking blood, or foul-smelling fluid (infection), or a lot of discharge on one side and none on the other could be signs of a breast abnormality.
So, if I were you, I would not be concerned about this.
