My baby is not moving as much as I like.

I'm 27 weeks and I already went to the to the doctor about this last week.. of course she moves like crazy while I was there but for 4 days before I didn't feel her at all and now it's been almost a week and still feel nothing after trying all the tricks. I call my doctor but it's the same thing saying she's fine. Also did any women experience bad pelvis pain getting up as well as while particles in your urine?
