HI I'm 21 yrs old and my breasts are leaking milk. I took a pregnancy test and it came back negative. My period ended so I'm no sure if I'm pregnant or what. I'm FREAKING out! Someone please give me answers. I know that if I were pregnant I would only be a few weeks.

It can be caused by hormone imbalance, certain medications, and even the Pill. You should see a Dr. to rule out anything serious.

Well, if you recently had sex, then it is possible that you are pregnant. However, since you just stopped your period, I would say that it is something to do with hormones. You have more of them running though you while you are on your period, so it is possible that your body created a little milk, and the only place for it to come out is your breasts.
If it does not stop soon, then speak to a doctor.
