Baby Growth reduced

Had a growth ultrasound on tuesday (36 weeks) and baby is 5lbs 4oz according to them. She was 5lbs 1oz two weeks before at 34 weeks. Theyve got me in for another ultrasound on tuesday. If she still hasnt grown much they will deliver early.

I know growth ultrasounds can be sooooo off. But has anyone had this before? X

Ps she is super active i feel her move and bulge out my belly so much so im not concerned at her movements. Shes engaged. Head down. & water & blood are good!
