Should I be worried?

So I felt the little one kick for the first time about a week and a half ago and once she got started, she did not stop. Night and day, she was at it. It got to the point where she would keep me awake at night! All of the sudden she's just stopped. I've only felt 2 little kicks today and I'm starting to get worried. Should I be worried? It doesn't matter. I already am.
