is it normal?

Lotus

I'm 37w and 3 days at my appointment today. My daughter is measuring at 33/34 weeks. And has measured that for the last 3 apts. My doctor says it's normal but I'm concerned he hasn't ordered a growth scan or anything and I just am worried she not growing I'm sure she is okay cause she moves a lot and heart beat is fine but how do I know she's growing
