Back labor?

My lower back has been hurting for the past two days, it’s a dull pain but worse today. It starts out with what I assume is Braxton Hicks but by the end of the contraction my back starts throbbing and then stops. It never starts at the beginning just at the end and the stomach contractions aren’t painful. It’s not a terrible pain by any means, I have a high pain tolerance and it’s mild but enough that I noticed and it’s making me uncomfortable. It aches constantly but definitely hurts more for a brief moment after the BH. Does this sound like the start of labor? I never experienced back pain like this last pregnancy and my contractions were very obvious and painful because my water broke. The back of my thighs are also tired and achy today. Google isn’t helping so I’m hoping someone on here can tell me something!
