ah I remember feeling the same way at 16 weeks - couldn't wait to feel something move, or a bump and at least see a bump!

I don't think I felt any movement until about 18 weeks or so - having said that you could be getting flutters and not realising what they are, that happened to me a few times - I just thought it was wind! but when I read stuff on here I realised it was fluttery baby movements!

You're on the cusp of the fun stuff!
