Insomnia sign of impending labor?

I know towards the end, we all have trouble sleeping due to being uncomfortable. But the last two days I may have gotten 5 hours of sleep max and it’s not because I’m uncomfortable. I generally have slept well my whole pregnancy but this week I’ll lay there for hours with my eyes closed and nothing happens, it’s driving me crazy. Does anyone have experience with this being a labor sign? I’m 39 weeks.
