Have you tried doing kick counts? Usually when you're closer to delivery the baby doesn't move as much because there isn't much room. The doc told me to make sure and lay down, preferably on my left side, and just relax. Count how many times your baby moves and if you don't get to 10 within one hour you should call the doc. Maybe you should try that if you haven't already. Otherwise I would suggest calling the doc to see if they have any other suggestions or cause for worry.
Honestly, it seems a little early in your pregnancy to worry about not feeling your baby move for one day. Are you working? Usually if you're busy throughout the day you don't realize if the baby moves or not, at least that's how I was.
