Pumping for a day away

I will be away from my ebf baby on Sunday and need to pump her a supply to leave with my husband. I tried pumping this morning about 2 hrs after her feeding and only got 2 ounces..is that normal? I thought I would have produced more then that! I pumped from the side she feed on last because she only nurses on one side each feed and it was close to time for her to nurse again so I didn't pump the other side.
