Who else is doing the bare-minimum this pregnancy?

I am normally very much an overachiever and take on a lot (full-time student, volunteering, work, now add in pregnancy and managing my apartment on my own as my husband works out of town). This pregnancy though, even with it being my senior year and some of my hardest classes, I'm finding it difficult to do the bare minimum, and procrastinate/just slack off a lot. I've lowered my standards a lot, specially because I'm just so mentally and physically tired all the time, even at 24 weeks. This is my first pregnancy, so I can't really say if it is really normal or not. I think I just need some validation that I'm not the only one.
