Bad pain in lowers uterus

I’ve been told it’s round ligament pain but I’m just trying to make sure. Im almost 29 weeks & right above my pelvis bone on the right side of my belly, I have a terrible pain every time I barely press on it and when I walk it hurts so bad. Is this just my uterus stretching or what could it be??
