After breast feeding, do you pump?

Brittany

I'm trying to figure out how I can build up a stash of breastmilk for when I have to leave my daughter for short periods of time with her dad. And possibly might have to go back to work early so I'd like to plan for building a stash of breastmilk. I pumped today after feeding and only got 1 oz total. I'm on medication to increase my supply, but I'm wondering is this a normal amount to be expected? Seems like barely any to me. Any suggestions?
