induction at 39 weeks first time mom

Serenitymay8

I'm being induced next Thursday at 39 weeks. Last night at the hospital they told me my daughter is only measuring about 35 weeks in my ultrasound. I'm 80% effaced and dialated 1/2 to 1 cm. I'm so nervous. They told me she might not be getting the nutrients she needs. But the ultrasound can also be off a pound? I don't fully understand and I'm a first time mom.So any advice would be greatly appreciated. I'm in Fayetteville Arkansas and going to Washington Regional.
