Okay, so I am a huge worry-wart...

Over the past few days I feel like my pregnancy has come to a bit of a standstill. My belly doesn't seem to be getting any bigger (not that it was very big to begin with). It seems less hard too. I used to have a huge appetite, where I felt like I needed to eat every hour - that seems to have gone. I haven't even eaten that much today, but I just don't feel hungry. And lastly, and the one I'm most concerned about is baby's movements. Sure, I only felt my first movements about a week and a half ago, but I'd then been having some strong kicks, and had been starting to feel him move throughout the day. Then yesterday I barely felt him move, and when I did it was very soft (barely noticeable), and now I haven't felt any movement at all since 2am. I've tried sitting down quietly for awhile, I've tried eating something sugary, drinking something cold, poking my belly... nothing. Needless to say, I'm getting worried. Should I be worried, or is bubs just having an exceptionally quiet day?
