So ive noticed i produce more milk on my left Boob&the pain is less so ive been feeding him on that boob but 2 days ago i starting noticing my right boob getting less hard by the day which i assume means my milk production is decreasing,so i decided to pump.after 3 attemps milk finally started coming out but its a yellow tone vs my left boobs milk which is in the whiter side...what does this mean? Help
