Real contractions vs braxton hicks

I have a routine appointment in about 3 hours so I'll definitely bring this up to my doctor but I wanted to ask here first. I'm no stranger to BH contractions at this point. When they happen my belly gets hard and feels tight. Its uncomfortable sometimes but never painful.

However, this morning, I've been feeling a similar feeling, but its more in the lower part of my uterus near my panty line. It was a more powerful tightening feeling and it wasn't quite painful either, just more unpleasant. The tightening feeling started out from my hipbones and made its way into the center. Was that a real contraction? Or just a lower BH contraction?
