IGUR Baby 28 weeks

I've posted about this before. During my anatomy scan at 21 weeks I found out that my baby girl was a little on the small side. 11th percentile to be exact. Four weeks later I got sent in for a growth scan and she dropped to the 5.4 percentile. Starting last week I had to come in weekly for NSTs and ultrasounds to check fetal movement and a cord Doppler. The cord Doppler showed that there was good blood flow but there was "elevated pressure." So, they sent me to the hospital for another growth ultrasound and now she's only at the 4th percentile!! They had me come back in for another NST which was normal and I go in for another one tomorrow with the BPP and cord Doppler ultrasound. I haven't got the chance to speak with my ob or MFM since the "elevated pressure" finding and have only talked to the nurse who told me exactly what the ultrasound tech did. I can't help but freak out! I really don't want them to take her before 37 weeks. Have any Mamas out there have any experience with this?
