22wks & I still don't feel baby movement

Kenndis
I'm 22 wks 4 days and I still don't feel any movement yet. During ultrasounds she's doing somersaults but I don't feel a thing. I'm a plus size woman and I'm figuring that's a part of the reason why but has anybody had the same experience? I'm also a 1st time Mom although I've had 2 previous miscarriages. My nerves r so on edge!
