A bit worried...

Hope
I haven't felt baby girl much at all today! I was just laying down with my hand on my belly and still nothing. It feels like a tiny squirm, but no kicks!
I'm going to take a shower and try again. 
Any advice?
I've had water, orange juice, even tried Gatorade for some sugar, pineapple slices, and I ate like normal today. 
Anything I haven't tried?
When should I call the doctor?
Please don't just read this and leave me hanging, I need some advice before I make an after hours call.
