30 weeks and baby hasnt moved much today

UPDATE* I got her moving this morning after drinking a big glass of OJ. Im exactly 30 weeks today and my baby is normally pretty active when I lay down or relax. Yesterday afternoon I noticed she wasnt moving as much and at bed time I couldnt hardly get her to move. I drank chocolate milk and was snacking before bed.

Now at 5am I just used the bathroom and laying back down. Im feeling some very soft, faint movements then back to nothing. Nothing like normal and no definite kicks.

So I feel some occasional light movements, Im just mot sure if I should call my Dr or wait and see when I eat breakfast if she starts kicking.
