I have noticed for the last few weeks that my left breast has been feeling as though milk is dropping! (I have a 17mo, busy haven't bf since she was 6mo) I have taken 3 test which all say not pregnant (which we are NOT trying) per my "PINK PAD" I was 3 days late, but I started last night (I don't always have bad periods, so me saying its lighter than most would be hard to say)! I have read that if this is happening it could me : Miscarriage Pregnancy (implementation from the period) Stimulation of nipples Hormones Can anyone explain to me why this could be happening other than google;) I really don't want to call the dr, but if I need to I will! I don't want to end up one of those stories "I didn't know I was pregnant"
