Advice for pumping while nursing twins

My twins are just 11 days old now, but I am looking for advice on how to schedule their feedings while still allowing time to pump and build up a stash for when I return to work when they are 6 weeks. I did it with my daughter, but with two babies this time around I feel it is going to be a lot different! I try to tandem feed as much as possible so they each eat on one side at a time, but afterwards I feel pretty empty and if I wait to pump it will cut into their supply for next feeding. Any suggestions are more than welcome!! Thank you!
