my baby is measuring way ahead any others?

here she is sucking her toes and being uncooperative. She refuses to show us her face or stay in a helpful position during ultrasound. She kicks the monitors off during nsts.... and now she's measuring 39 weeks although I'm 32 and 6 days... doctor may deliver her early and although excited to see her I want her to continue to grow inside. any other mommas measuring that far ahead?
