Is it possible to have an oversupply in only one breast? My left breast is fine, producing normally but my right breast constantly feels engorged, produces less than normal and is soo sore 😭 im exclusively pumping so idk if i should be pumping longer to help empty it or if that would make it worse...? I've been using a heat & vibration lactation massager before every pumping session but it doesn't seem to be helping.
