11 weeks pinching pain?

I’m 11 weeks I had a check up ultrasound today because I have a subchroionic hematoma but everything looked Great on the ultrasound and you could see the little baby wriggle around and good heart beat.

Well now I’m hope and just had to drag myself up stairs because I’m having sharp pains on the right side of my belly. It’s almost like a sharp pinch and it comes and goes. It gets worse when I move my right leg too. Otherwise I have my normally achey belly like I’ve had this whole pregnancy but this really hurts and keeps coming back and going quickly. It’s just in one spot on my right lower belly. Has anyone else had this experience?
