hj1981, I didn't feel movement until just after 20 weeks, even then it was just butterflies. I remember being at my 20 week scan, we could see bubs moving around like crazy and DH was amazed that I couldn't feel a thing!

So I wouldn't be worried about not feeling movement for quite a few weeks yet. Enjoy your sleep now, before long you may be kept awake by kicking until the wee hours!
