Horizontal baby

At my last 3 ultrasounds baby has been completely horizontal! Her head on my right and her feet on the left, with her back out.

The ultrasound technicians have had the hardest time getting good pictures and measurements even after I run in place, do jumping jacks and empty my bladder.

Is this normal?

Anyone else have a horizontal baby?

How can I get her to move for our 3D ultrasound on Friday at 28 weeks?
