How many oz are you pumping at 13 weeks pp?

My baby girl is 13 weeks and I am pumping anywhere from 24 oz- 30 oz a day. It’s different each day by a few oz. Is this an average amount? I have about 6-8 bottles of milk in fridge at a time. She eats about 20-24 oz a day sometimes a little more. I’m just concerned that I won’t be able to keep up or that she will want more and I won’t have enough for her.

Any advice and similar stories appreciated. Thanks ladies!!!
