Is it possible to be too tired?

About 2 weeks ago I hit my nesting stage but since about Sunday, I haven't been able to get enough sleep it seems. Yesterday I slept pretty good in the night (considering I'm carrying a giant child and all) and had a nap before work and I was still exhausted all day. I hardly wanna get up to do anything 😩 any other mamas having this? I'm 37 weeks and 2 days
