Baby movement

I'm 28 weeks as of tomorrow, but haven't felt baby move all day. I did drink some cold oj and lay down for an hour, but still nothing. I used to feel baby very strongly, but since baby has been head down it's been less noticeable because my placenta is in the front. Drs is closed, but should I go to l&d or give it another day and see? I ask because I've heard that even at 28 weeks this is common as they too have their lazy days and growth spurt days.
