Stomach pain- 5 weeks

I’m 5 weeks today and since this morning I’ve had really bad stomach pains. The pain is at the top of my torso in between my rib cage. The only way I can describe the pain is kinda like how you feel when you haven’t eaten in a long time and your stomach physically hurts? I’ve had that pain on and off all day long and I’ve eaten!

Do you think it’s pregnancy related or something else?
