35 weeks. Pain in upper right belly?

calm down

Is this normal? I've had it before, but usually its after walking or standing a lot. I've been having this pain this morning, but I havent really been doing much walking. It hurts to stand, and gets increasingly worse when walking so I have to stop and sit down. It doesn't feel like there are any contractions. Could this be baby in my ribs? Round ligament pain? I'm used to having round ligament pains but typically that's in my lower abdomen.
