You sound just like me 1.5 wks ago in regards to movements. I couldn't feel any definite movements, just a 'shift' which sounds like what you described. At my scan they told me the placenta is anterior, which I had read about, so that was why I couldn't really feel anything. But now every day I feel her for sure, especially today... it would seem she's having a party in there. Obviously realised she as room in there atm and she ought to enjoy it!
