Flutters or Gas?

I have been feeling "flutters" the last few days. Mostly when I am lying down on the couch and a lot of time when I am sleeping. I will feel something during the middle of the night and think I am awake and then wake up and not remember if I was awake or dreaming. Today, all day, I have been feeling swirling movement in my abdomen. Most people will say it is probably gas but it feels different and feels like it is in my uterus, not in my intestines or stomach. Who knows? I guess time will tell.
