Anyone else have issues pumping where one side produces more than the other? I just pumped and my left breast gave 3.25oz & my right only had 1.25oz! It's been that way for a few days now as well. I'm only 12 days pp, but are there any reasons why one side would be producing more than the other? I did realize today that I always start with the left. Could that be a reason why? Any help is appreciated!
