How to increase my milk supply!?

[Marquez__]

I pumped for the very first time on Thursday, I got 4oz total.
My boobs were huge until I pumped they literally like shrunk :/
And ever since then, when I pump I barely get an ounce to an ounce in a half :/
I really hate that my daughter is having to be on formula cause I can't produce enough.
What are ways or things I can eat/drink to increase my supply?

Keep pumping. That amount is totally normal when starting out. Just keep it up every 2-4 hours. It will begin to increase. I heard fenugreek is good for increasing the amount
