Am i in early labor

My lower back is killing me, i feel nausous, my belly is tightening up but it doesnt hurt that bad, im shakey and have a bad headache.

Sounds like normal pregnancy stuff and possibly Braxton Hicks contractions

That just sounds like normal pregnancy stuff, especially 3rd trimester stuff. And you're probably having Braxton Hicks

probably normal...braxton hicks. always time the contractions. my contractions didnt hurt bad to begin with. i waited like 5 hours before going to the hospital...when i got to the hospital is when the contractions started to hurt bad.
