Baby balling up or Braxton-Hicks???


So yesterday while i was in the car i felt my stomach tighten up almost like he was balling up in the middle of my stomach to the point I’ll lose my breath for a moment or two then it would come back then just goes away

Then last night while i was laying on my side it happened again I’m confused cause I’m not sure what it is???

Never had these with my last three?

Could it be the baby or just Braxton-Hicks!!
