Has anyone had IUGR picked up at their 20 week scan?

I had my scan almost 2 weeks ago now and they noted my baby was small (1%ile) so I was sent to the women emergency directly from my scan for some further testing.

At my follow up appointment last week the doctor spoke about the scan and how I will now be transferred to the Maternal Foetal Medicine team as I am a high risk pregnancy. He said I will be having fortnightly growth scans and if there is any sign of baby dropping back in his growth they may have to take him out early (any time from 25 weeks onwards)! Im trying to remain positive that I’ll get to 36 weeks, however I’m terrified! Has anyone dealt with this?
