Hi- Congrats on being preggas-
I didnt feel movement with my first til the 16-18 week mark but this time i have been feeling movement already. They say that with your second, third etc you are more receptive to the feeling so you feel it quicker. I wouldnt worry too much i have friends preg with their first and hadnt felt anything till bout 19-20 weeks. It will happen and when it does it will make it more special.

Usually i feel bubs more when i'm relaxing or sometimes a cough or sneeze can set the little one off. hehe... Good luck
