i'm guessing you'll get more helpful advice, but i saw no one had responded yet.
things like drinking tons of water, eating oatmeal, eating lactation cookies (you'll be able to find a recipe online & they are heavenly... seriously!), block feeding, feeding on demand might help up your supply. pump output is never a good indication of supply because your baby is always more efficient. if those things don't work, you could try mother's milk tea (i've heard it tastes terrible, but works) or other supplements like fenugreek or domperidone that have been shown to increase supply.
good luck!
