Advice from experienced moms please!!! ..was this the baby moving or something else?

As a mommy of 3, I would have to say that the symptoms you described sound much like gas or indigestion. Your baby is probably still too tiny to feel his/her little kicks, so it is likely your own digestive process. You could call your doctor to listen to the heartbeat and to verify that things are okay. I could be wrong of course, so do call your doctor for sure. Congrats on your pregnancy :) Take care of yourself.
