My baby hasn't moved

29 weeks (30 on Monday) and she isn't moving. I had the same problem a few days ago and the doctor hooked me up and said she was perfectly fine. But it's been two days and I feel like very small stretches but no kicks at all and no turns or rolls. Nothing. I feel like I keep crying wolf but it's hard to not freak when it's been two days and your baby doesn't move at all while you're awake. I felt a few small jabs in the night but that's it. 
Any opinions on what to do?
