I felt movement at 17 weeks. It was only because I could tell that the movement was coming from within the new lump in my abdomen that I could tell what it was, though. I felt something, knew what it was, and then started telling myself it couldn't have been, because everyone says first babies can't be felt until 18 weeks, but everyone lies.

It was like an excited stomach-swoop feeling, only quite obviously not in my stomach. It fluttered and bubbled. It lasted almost a whole second, and hasn't recurred since, but then, I haven't been that awake and that still and that relaxed since.
