Newbie Pumping Q's

retallica

So I have been EBF DS and recently (like the past week and a half) have been pumping 1-2 times a day usually once, to try to get a small freezer stash going and get used to pumping before I return to work.

He has gained weight great since birth and has tons of wet/poop diapers. I have been pumping about an hour or so after a feeding. At first I barely got a few drops but now I have been getting about 2-2.5 oz. Is this a normal amount? I feel like I should be getting more, but I don't really know what I should be expecting.

It seems like I get a little more each day. Should I pump more often throughout the day? I have been just doing it primarily once a day, sometimes twice. Should I pump after every feeding?

Now I am worried that I have a low supply or something! Talk me down ladies.
