Are these Baby Kicks?

So, Im almost 22 weeks.  Ive been trying to see if I can feel the baby kick.  Not sure if what Im feeling are kicks, or muscle twitches, or my pulse.  Haha.  The first time, I felt what I can only describe as a poke on one side and then a poke/muscle twitch on the other side.  And then I felt a muscle twitch in my shoulder that felt exactly the same.  Therefore, I can only assume they were just muscle twitches.  Sometimes when Im laying down I can feel a few kicks, but then I realize its my pulse (*unless baby's got AWESOME rhythm).   I know Ive heard it feels like gas bubbles or something in the beginning and thats not really what Im feeling.  I dont know.  Any thoughts?
