Quickening or Just Gas Bubbles?

It's so hard to tell! I started to become especially aware of these sensations on Thursday night, as I was lying in bed. I have a feeling it was just gas bubbles and other random digestive gurgling sounds since I ate a huge salad for dinner, but then again...some of the sensations felt like a rapid succession of tiny little bubbles whirling in my lower tummy. If it was just gas, it was definitely different from what I usually feel. From reading blogs and online forums, it seems a lot of women have trouble distinguishing early fetal movements from gas bubbles, but generally as the pregnancy progresses, it becomes more obvious which is which. I cannot wait to feel Ziggy for certain--for a brief moment when I was convinced that I had felt him/her move, it made me so blissfully happy, I actually started laughing. AC had already left for his weekend Martial Arts training, otherwise I would have called him to come feel my belly. When I put my hand there, I could definitely feel stuff going on, but again, it could have just been my wacky digestive system. The fact that these sensations occur after I eat probably means it's not Ziggy, right? Oh well, I suppose I should stop obsessing (but wait, isn't that what I do best ;) and just wait and see.

PS: I didn't receive a call from Dr W's office yesterday, so I guess that means my screening test came back negative! Woohoo! I realize this doesn't absolutely guarantee Ziggy wont have those problems, but it does ease my mind a bit.
