If you are not pregnant and are having discharge from your breasts, then you should go to a doctor.. that isn't normal..
I would see a doctor to rule out a variety of things both psychological and physical. It could be as simple as the stimulation of the breasts from sucking causing an increase blood flow and leakage, or a change in diet, or certain medications or an enlarged pituitary gland, and of course pregnancy. I would see a doctor as soon as possible - do not wait to check if you are pregnant with a home pregnancy test first. Good luck.
Well, if you are asking if you are pregnant, no one here can really answer that. Have you taken a pregnancy test? I strongly urge you to see your Dr. Perhaps you have an infection of some sort? I honestly don't know how to answer this, but when in doubt, seeing a Dr. is usually your best bet. Good luck.
