30 weeks. Braxton Hicks?

bridget 👼🏼 👶🏼👶🏼

I am 30w 3d pregnant and my stomach feels insane. I had my usual breakfast but for some reason I am cramping or something that feels like a knot in my stomach. Are these Braxton hicks? Or should I call doctor. I am not bleeding just cramping that feels intense for a few seconds and starts from my lower back.
