i’m ebf lo is 5 months old. i’m barely pumping 2oz I have no clue why my supply dipped all of a sudden.. my right nipple has been hurting and i didn’t know why bc it’s not cracked or bleeding looks normal except when I touch it and rubs onto my clothing.. I still feed her from that side and pump as well but hurts like crazy.. I was feeling for anything and I felt a knot where the pain is.. felt the other nipple and that knot isn’t there.. anyone know what this could be and if it’s causing my supply to dip?
