Back labor..?

Ashlynn • Married and mother of 2 perfect little boys with a sweet baby girl on the way- due in October 👻💕
I'm not sure if I'm having back labor or not..I've never had it before and not really sure what it should feel like.. 
The pains I'm having feel like they are deep in my lower back and it feels like I just got hit by a truck..they will come and go, and they last for awhile..I've been having these pains for the past like 2hours..maybe even longer. I feel so miserable.. 
Does this sound like back labor to anyone? Or is it just a terribly sore back?
