I would see a lactation consultant and talk to them about your previous experiences and see what they think. You can eat foods and take supplements called galactagogues. They are foods and supplements the help naturally boost milk production. Oatmeal is one that really helps give me a boost.
Talk to an LC, or maybe if it happens again at try using a nipple shield.
Just take the baby off every time it bites just long enough for your baby to understand it's not acceptable behavior. I gave my daughter her binky whenever she got in a biting mood and by the time she got teeth she rarely bit.
