Help!

Deyona
So I was EBF but i seriously hate it. So I want to pump. I've been pumping for a few days but I feel like I'm not getting enough. I only get about and ounce out of each. And my baby usually eats about 2 oz at a feeding she's 2 weeks and 2 days. How can I up my supply? How often should I be pumping? Please help! I don't want to give her formula but I dont know if I'll be able to make enough milk for her :/
