I had an issue like this, my left breast always produces less than my right, and while annoying, my right breast makes up for the lack and there is plenty for LO, being lopsided isn't much fun though, lol. I do know you can encourage milk production through nursing, and at 3 weeks you still have a good chance of evening things out. With my first son I had an inverted left nipple and by the time I figured out how to help him to latch on it was too late for my left side, lol, it stayed at least a cup size smaller than the right, and usually produced about 1/2 ounce less than the right.
