baby is 7 weeks pumping schedule

March🕉
So I'm EBF but pumping during the day for feedings and nursing my baby girl for the night and early morning feedings. 
I pump every 2-3 hours and get between 3-4 ounces total. 
I feel like I should have more of a milk supply. What's everyones else getting at about 7 weeks postpartum ?
