Uneven Breast; Milk supply

Katie

The past two days, I noticed my left breast is always feeling engorged and not my right side. I can tell they are definitely uneven because whenever my husband and I are out, I pump and get about 4 oz on my left but only 1-2 oz on my right. What can I do to even them out? My baby also does not like latching on my right as long as the left due to it being a slacker boob and not enough milk is being produced.
