Infrequent movement?

First time mom here, and I'm a little worried that my little girl isn't moving much. She kicks up a storm like clockwork every morning at the same hour. Today, nothing. I poked and prodded my belly and maybe got a slow movement. She kicked once or twice, and now nothing again. I tried drinking lots of water and eating and then laying on my side. Nothing. I'm kind of worried, but haven't gotten to that less than 10 kicks in 2 hours standard yet. Anyone had something like this?
