My nipples have been leaking like this for months now and I haven't gone to the doctor I also have a bump in my right breast is this an infection? Also threres no way I'm pregnant

You should see a Dr. to rule out an infection. Sometimes, hormone imbalance can cause the discharge, but the Dr. would help you determine that, too. Good luck.

My breast are leaking a greenish color and the Dr. don't know what it is who more should I do I have a history of having MRSA

Go to the doctor. Could he hormonal, could be infection, could be something more serious so get over the shyness and go.
