I have the strangest thing going on. My milk supply goes up and down like crazy. Or rather, my breasts feel heavy and large for two days and then they feel soft and emptyish on other days. Towards the end of the week is when I feel like I have an oversupply, while the rest of the week I usually feel fine. Why does this keep happening? My LC says that you can't go from regular supply to oversupply (or undersupply) in a matter of hours. She says something might be off with my hormones. Does anyone know anything about that?
