I have been reading online that when you do self exams for breast cancer to check for liquid coming out of your nipple. I have a thick, creamy liquid that come out of my right nipple (when i squeeze it). I am on the birth control shot, and have been up to date with every single one. I have also taken 4 home pregnancy tests through out a four month period of time, and they all were negative. I have been pregnant before and I dont feel like this is the reason for the liquid. Does anybody have any suggestions, and does it sound as if it could be breast cancer??
