Should I still pump?

Me

My baby is 3.5 weeks old. I was pumping since my supply was more than he needed. Now I am using a haakaa to catch the leaking on the side he isn’t on. Even that is enough to get about 2 bottles each day if I want my husband to do a feeding and he gets full from me. Should I still be using my electric pump? I want to keep up a good supply and even a bit of a stash for emergencies.
