Sleeping through feedings

I think my little guy is going through a growth spurt since he’s been sleeping a lot, he’s 7 weeks old. When he’s awake he eats every 2 hours on the dot but he can nap for 3-4 hours. Wellll my breasts start leaking now every two hours and when he sleeps through a feeding they feel pretty engorged. Should I pump even when he is asleep to keep up my supply?
