Braxton Hicks or contractions?

So for about half of the day starting around 5pm I’ve been getting what feels to be Braxton Hicks every half hour. They are kinda painful and then may hip and lower left side of my abdomen start to tighten up. I also feel pressure in my lower back when these happen. It’s not super painful or anything just uncomfortable so I’m not sure if they are contractions or not?
