Don't 'feel' pregnant!

I honestly thought that when I got to 16/17 weeks I would feel pregnant but here I am going on 19 weeks and I don't feel a thing, not even a flutter.. I don't even look pregnant in the slightest. I think with people starting to ask if I've felt anything yet and saying 'no' all the time is stressing me out???  There has to be someone in the same vote :(
