It could! I had back labor with DD, and after a couple times of telling DH "Man, my back hurts!" at 2:30am, and then having it go away, he said, "Do we need to be timing this???" I had no idea they were ctx!! In fact, I think I posted to my DDC that I *thought* I might be in labor...wasn't sure...then eight hours later, there was DD!!
Especially if they are going around to your belly, and are coming with any regularity, I would say yes!
I would note how close they are and how long, then maybe call your provider just for a heads up. Good luck!
