Lack of movement

I'm 30 weeks and went to my obgyn yesterday and heart beat was good . I felt some movement this morning but nothing since:(  I've heard baby can have days where they don't move much, and my baby isn't a huge kicker anyway... I've tried orange juice,  sweets, water nothing is working!! Any ideas? Or should I go to l&d?  I'm trying not to freak out over nothing.. Tia!!
