Crazy energy before labor?

Terri
So last week at almost 39 weeks, I felt exhausted, run down and ready. Now a week later, due this Sunday, I've had an incredible amount of energy the past three days. Does this happen right before you go into labor. Anyone else experience this and give birth shortly after? I'm talking : baking cookies at 9:30 last night, then cleaned the stove and counters, then put in a load of laundry at 10:30pm to run this afternoon....etc.
