Change in movements at 35 weeks?

Since hearing amanda holden has lost her baby i am a complete paranoid freak! I fell my baby less and the movements i do feel are not as severe as before. I am 35 wks today, could this be down to something serious or is it just down to the fact that he no longer has much room to give me the big kicks he was before or to make my tummy move as visible as it was before? any advice would be great xx
