Upper right side pain?

Cougar

Hello! I’m 25wks pregnant and I’ve been having this intense pain in my upper right side. It’s been going on since yesterday morning and at first I figured it was just trapped gas or something, but it’s not getting any better. I’m wondering if maybe it is just gas? Or if there could be something else going on? It’s 7am and I’ve been up since 4am in pain because of it😩
