IUGR, baby measuring in 5th percentile

Arianne

I had a subchorionic hematoma very early in my pregnancy and it resolved itself by 18 weeks. My due date was pushed up a week and everything was looking great until my last ultrasound at 23 weeks and 2 days. I was told she was only 1lb 1oz and was measuring in the 5th percentile. I'm now 27 weeks and 3 days and am going to a high risk doctor tomorrow to be monitored with level 2 ultrasounds. Should I be worried? What could this mean?
