energy burst??

To
For the past 3 days I have NOT BEEN TIRED AT ALL! Thursday night I didn't go to sleep until 5:45AM. I laid awake watching tv from about 8:00 until I made myself go to sleep at 5:45. Next day, no nap, not tired, finally took Tylenol pm to make me sleep, then today I've been going strong all day long and here it is 11:40 and NOT tired. Could this mean labor is soon? 38 weeks Monday.
