I think I felt the baby move last Friday 17w2d, but I'm not sure. I was sitting in the recliner and felt what I can only describe as 3 taps low in my abdomen toward the left side a bit. It didn't feel like gas or butterflies, and I know it was much lower than my stomach. I haven't felt anything like it since then, but I don't sit still and just relax very much, either.
