Fatigue before labour??

Tori

Went to bed at 10:30 last night, woke up a few times in the night but only for a few minutes at a time, woke up properly at 11:30am and now at 2pm I'm half asleep again. Also had an increase in Braxton hicks since I woke up this morning. Has anyone experienced anything like this before labour started? (I'm 39+6)
