Fetal Growth Restriction

Wondering if anyone has had experience with fetal growth restriction? At 29 weeks my baby was measuring at the 62nd percentile(and had been right around that the entire pregnancy) Now at 32 weeks she is only measuring the 7th percentile.

I will go in weekly for ultrasounds now; but obviously I’m super worried. From what they can see it’s not a placenta or umbilical cord issue.

I am 37 years old, and had the quad screening for chromosomal abnormalities at 10 weeks and I was very low risk for everything.

If anyone had experienced this I would love to know more info!
