Where is baby at 19weeks?

I’ve been reading that the uterus is only to the belly button at 19/20 weeks. But last night I was laying on my left side and while adjusting position I had sharp pain in my upper right belly and ribs. It lasted for several minutes. Definitely above the belly button. I’m just wondering if this could have been the baby? I haven’t felt any firm movement yet. Just flutters and they’re usually below my belly button.

With my first I never experienced rib pain or “baby being in my rib area” so I don’t know what that’s like.
