Okay so since I had my baby my boobs have been double d size and producing 7 oz from each boob in 10 mins . Today I woke up and my left breast is the same size it was before I got pregnant but the other one is still big , my milk supply also decreased in the boob and only got 3 oz in 10 mins. This literally happened over night . Yesterday I was fine produced 30 oz and boobs were normal. What is the cause of this?
