There's always a chance of a woman being pregnant, even with 2 negative HPT. But, like Kim said, it sounds more like a hormonal issue than pregnancy. You should make and appointment with your doctor.
leaking white coloring form your breast is not a isgn of pregnnacy....its a sign of a hormone issue going on. and you do not have like any other symptoms...such as a missed period or frequent urination.
your gettinga negative hpt...chances are your not pregnant....you said "if i can still be pregnant" when were you pregnant before?
