I had the same thing happen to me with my first baby when I was as far along as you are but I didn't feel any movements, and after much worry, panic, and a two hour drive to the nearest medical imaging centre for a scan, we found out that he was just in a real deep sleep and was just fine. It is really worrying though, so if you still can't get bubs to move more than what she is by trying either a shower, ice cold drink or even something really cold on your belly, then call your caregiver or hospital and see what they recommend you do.
