NST 2x Week, US once a week, and possible SGA

After my last ultrasound at 27 weeks, it was determined that the baby is in the 7th percentile. Because of this, my doctor ordered NSTs twice a week and US once a week. She mentioned that if the baby gets to 10th percentile I can stop coming in so frequently.

I have a hx of pre-term labor (first one was 8 weeks early and they never found out why). I'm so nervous this one will be pre-term as well AND I'll have to live in the NICU again. I was really hoping for a "normal" pregnancy...

Anyone have a similar story?
