I don't pump regularly, and EBF, but I get between 1.5 oz and 2.5 oz from both breasts if I pump within a couple of hours of a feeding. I have gotten up to 4 oz if it's been longer, but that's been only a couple of times. I pump before I go to bed or after the first morning feed, with the intention of having a small freezer stash for DH to watch LO if I need/want to go out by myself. We don't feel comfortable with the ILs watching LO, and my parents live too far away.
From what I understand, the more you pump, the more you will produce; the same as for feeding directly from the breast. And if your DH feeds your LO the pumped milk, you should pump for that session, too. Especially since your supply is still regulating. Good luck with your pumping.
