should I take a nap?

I'm 38 weeks pregnant. I'm extremely exhausted and it's about 6pm. I feel guilty bc I have so much to do. The house is a mess. My boyfriend just left for work, and we still have presents and stuff that still needs to be put away, not to mention all the laundry that needs to get done. But I'm sooooooo sleepy:/ especially bc we've spent the last three days doing so much for the holidays (visiting family and such)
