Could this be movement?

Let me preface by saying that I have always been in tune with and hypersensitive to any changes in my body AND this is my first baby.  The past few days, I've felt a teensy, tickly, tugging or twitching feeling way down low when I sit or lie very still at the end of the day.  It doesn't happen often, and it doesn't happen every day.  I have also had epic rumbly gas, but THOSE movements haven't been teensy at all.  I am 12 weeks 6 days.  I keep flip flopping on whether I think this is the baby or just a new type of gas experience.

What do you girls think?  What has been your experience?
