You shouldn't pump until at least 3 weeks when your supply is well established. A pump is not a good indicator of supply. You really need the baby to be nursing to up it. Missing a feeding will only tell your body not to make milk at that time, even with the pump, it takes constant pumping to increase it like your baby would. If you're going to keep pumping, turn it up to max until letdown, then dial it back. Stay hydrated & relaxed or let baby nurse on one side which can help with output from the other side.
