Low fluids & drop in percentile of growth?

Tiffany

I went in for my 35 week appointment and they done a growth check up again(I am high risk so they have had to do a few ultrasounds). My babies weight decreased from 61 percentile to 54 percentile and then today it has dropped down to the 35 percentile. Also, the ultrasound tech said I "only" had 9cm fluid around the baby. I feel like these numbers are alarming especially when decreasing like they are. Any advice or Anyone else been through this and baby turn out okay? (I'm high risk due to multiple miscarriages and losing fluid with our stillborn daughter at 26 weeks. They also said she was just a "small" baby but we lost her so quickly without any warnings)
