Breastfeeding help

Baby is 5 weeks old and is starting to sleep longer stretches. He’s exclusively nursing and I am not pumping (trying to minimize the extra work and maximize sleep!). All I do to build a freezer stash is use the haakaa on the opposite side during night feeds.

My baby is now sleeping longer stretches but I’ve been waking up at the 5th hour with my boobs hurting and leaking. Should I be waking up baby to eat then or should I let him sleep and see how long he can go? Should I try to get through the pain or should I be pumping? My fear is having to wake up to pump and then 30 mins later or so he wakes up hungry but my boobs will be empty, and then I also just had to be up at night even longer to pump and then feed him anyways. What should I do?
