Wide awake. 8-D

Is this a normal thing at nearly 38 weeks pregnant? I am NOT tired. I cannot even convince myself to be sleepy anytime it is dark. I want to nap during the day, but once it gets dark I'm alert and want to clean, etc. I've always been a night owl, but normally I can fall asleep no matter what time of day it is. Well...hopefully I won't go into labor after a sleepless night!
