Right breast produces more (Kind of long)

My daughter is currently in NICU, 16 days old. She came at 33+6 by emergency c section and while in the hospital I pumped every 3 hours. The hospital sent me home with a hand pump while I waited for WIC to provide me with a double electric pump. Anyway, my right breast always makes almost twice as much as the left breast. I can pump both breasts for the same amount of time and halfway through I have to switch bottles for the right breast but the left breast barely has half an ounce. The pump is working on that side , I switched them and the bottle filled so it's not the pump. It's my breast. How can I increase production on that side?
