Anyone going through this too?

I'm 35 weeks and 4 days and I've been having growth ultrasounds because my baby is small (30th percentile) until today when all the ultrasound measurements are less than 2nd percentile. They said she only weighs 4 and a half pounds and I have to go see a high risk doctor for another ultrasound in a few days. The nurse practioner wanted to send me to labor and delivery until the high risk Doctor said just make an appointment for Thursday or Friday. Now I'm nervous and scared and don't know what to do with myself waiitng. I've gained almost 40 lbs with this pregnancy too I don't understand, I just want to be able to bring her home healthy.
