Too little movement?

I'm 26+3 today, and getting a little concerned about baby girls lack of movement. She wasn't quite as active as she usually is during the same time last night, and only gave me a few light kicks this morning. Around this time of the day she's been dancing more generally. Reading that post from the other day isn't helping much either! I'm going to drink some ice water and juice and lay down but I'm hoping she's just tired today... Anybody else have a lull in movement for a day or so?
