burning pain/ pulled muscle?

Me
I tried to get in bed this morning and started to feel a burning/ aching pain on the right side of my bump from my ribs down past my belly button. I worked last night but only walked, no heavy lifting. I feel the pain most when he moves or when I bend or twist. No bleeding or spotting. I'm not sure if I should call my doctor tomorrow or just wait and see if it gets better on it's own. Any advice appreciated
