Anyone know why my stomach keeps vibrating?

Kind of feels like my heart beating, but faster and I can feel it more around my stomach.

Started happening early this morning, got no clue why or how it happens. I checked CDC and some other site, and it seems I don't have symptoms of stomach cancer nor diabetes. I think it's type 2 diabetes that runs in the paternal side of my family, and I do eat and drink fast food and soda a few times per week.

Should I contact my family doctor if this continues for a few days? It only vibrates when I'm sitting, standing, or lying still; moving around prevents it somehow.
