I have been doing pretty well lately with nursing and pumping so I contacted a milk bank a couple of days ago to begin donating. Yesterday, my right breast drasticly reduced in supply all of the sudden and the left breast has increased supply (to the degree that they are lopsided). I am making just enough to feed my LO but before I was making a bag (6oz) extra every day or so. I have not changed anything. Any ideas about what is going on? I am increasing the pumping and nursing on the right side in hopes that it will return to normal but I will be at a conference for the next 2 days and will only get to pump a few times and will not be nursing at all. Will I loose the rest of my supply? What do I do?
