Nesting but not supposed to be walking around too much?

Okay I'm 27 weeks and 6 days and it's 3am. I woke up to go pee and all of a sudden I'm like when everyone else is awake and at school/work I really want to clean this entire place. The issue is I'm currently considered at risk for preterm labor and I'm supposed to be resting as much as possible (not bed rest completely thankfully). But I'm so bored! And there's so much to do and I just want to get it all done. Any tips on how I could still get quite a bit done today without over doing it?
