Could I have harmed baby?

I was sitting on the floor and had to get up fast. I actually almost lost my balance and fell. It caused me to strain my abdomen.

I'm feeling a muscle ache kind of right where my stomach crease is (if that makes sense).

Could straining to get up like this cause harm? Or am I just feeling a muscle ache because my abs have gotten zero activity lately?
