Upper abdomen pain? What should I do?

Molls

I’ve had over 40 constant minutes of straight up uncomfortable upper abdominal pain. I was just laying there and baby boy was kicking and rolling away when all of a sudden it felt like my whole chest/upper stomach was in knots. I’ve had this happen twice before but both times only lasted maybe 15 minutes. And it happened weeks ago. Is this baby pushing on something or is it more severe? Has anyone else felt this? I am 29 weeks.
