baby or beans & rice...?

I keep reading in books that the first time the baby's movements are felt is between 16-20 weeks. For first time mothers, it is supposed to take a bit longer to really feel the movements, but yesterday and today I have felt some strange sensations in my abdomen that could be little kicks! Of course, I had beans and rice for lunch, so that could be the culprit, but I thought I'd at least put it down on the blog so that I can have a record of what MAY be first movements! How exciting!! I'm sure in a few weeks I will be able to tell if my hunch was correct.
