Increase in energy before labor?

Has anyone noticed a sudden increase in energy right before going into labor?

I went walking tonight at the mall with my kids (tons of fun 🤦🏽‍♀️) barely got in a mile. But once I got home I went through my older sons closet and completely purged everything that doesn’t fit him anymore, separated the clothes by save for the next 2 boys and donate. Now I’m doing laundry and folding and putting away along with straightening all of our bedrooms. Wth.. I have not had this much motivation my entire pregnancy.

So I’m wondering if this could be my nesting finally kicking in (because I really haven’t felt it at all this pregnancy)? My oldest son was the only one that I went into labor with on my own and I cannot remember if I was nesting like this right before he came.
