is it normal?

I'm 22 weeks and 5 days and still don't really feel my baby move. I may feel her move occasionally but only a couple times a week and it's inconsistent. Everytime I have an ultrasound she's moving like crazy. At my 21 weeks scan she wouldn't stay still but I can't feel it. Even when I'm laying down and still. Is this normal? I'm really worried because everyone says I should be feeling it. I may feel a few kicks like twice a week but that's it.
