Fatigue at 38 weeks..

S
I have never been so tired in my life. I sleep in until 2 pm then take a nap from 6-9 pm. Granted, I stay up until 3 in the morning (my husband works nights and it's the only time I get with him) but I'm seriously so tired all the time:( I can't function or go grocery shopping or clean because I am a zombie.. anyone else have this issue this far along??
