What are these pains 😭

I'm 36.3 weeks, and woke up today with pains in the circled areas. The pain is mainly where it is circled above my belly button and it's like a sharp pain when I stand or lay on my back. When I'm on my side the pain isn't as bad. Then occasionally I feel it below my belly button but not as often. I have an appointment Tuesday so I wanted to see if you guys knew what it could be before I wait or go in. Baby girl is moving normally.
