I am not leaking where it is noticeable but if I sqeeze my boob and nipple, something like thick milk or pus comes out. It isn't quite clear but not too thick. What is that? Is this something that happens when you are about to start your period? I have never noticed this before ever but one other time, when I was pregnant forever ago. I took a test today but it was negative. So I am stumped.:confused:

Could be from hormone changes around the time of your period or at other times. Higher prolactin levels, for example, can cause some leakage or being able to express a bit. Some women will be able to express some drops of fluid long after having had children. If it causes you concern see your doctor.
