Should I worry?

Mickey

My baby is staying on her curve. Shes in the 10th percentile but the doctor doesnt seem worried. Shes breastfed. But since ive gone back to work the last month, i pump at work. I only pumped 2-3oz when I pump. Should I worry that Im not producing enough. She doesnt seem hungry when she comes off of my boobs when I feed her at home but I know for a fact she drinks a 6 oz bottle. Is it my pump? I have the Medela pump and go. I drink tons of water and sleep well.
