Baby stopped growing?

C

I had my 31 week antenatal check on Monday and they told me my baby is small and hasn’t grown since last check which was when I was 28 weeks.

They have me booked in for a growth scan this afternoon.

What’s the outcomes? Give me both positive and negative as I like to be fully mentally prepared.

I know I should wait until my scan until I think to much as the measurements could have been wrong but I need to know or I’ll drive myself insane.
