Strange movements in stomach region

For about 2 weeks now I've had an odd sensation in my upper stomach area.  It feels exactly like a baby in the later stages of pregnancy moving around, but I'm definitely NOT pregnant.  It does not hurt nor is it constant, but it is perplexing to me.  What could this be symptomatic of?

Bloating, burning, burping...anything of this? Constipation, heartburn, nausea, early satiety? Exact location?

None of those that I've been particularly aware of.  It's directly below my ribcage.

In the middle is the stomach.
About 5 inches to the right it is gallbladder. Liver is over the entire rtight side below the ribs.
If it is just a vague feeling all over the bottom of the rib cage, it may be from trapped gas in the colon.

If that "moving" is the only symptom, it is hardly called a disease, so...but if it is annoying, then try to tell some additional symptom. Something occurs shortly afrter the meal?
