Feeling weird before labor?

I'm 37 weeks and woke up this morning feeling weird. Hard to explain but kind of like anxiety. I've had soft stools the last 2 days and been soooo hungry! Today I feel so weird and my stomach feels unsettled, somewhat nauseous, jittery and baby has been really active. No contractions but a couple cramps. Does this sound normal or am I just having anxiety for some reason?
