Possible UGR?!

Alyssa

I am currently almost 31 weeks pregnant & my 29 week ultrasound showed the babies abdominal circumference measuring small in the 5th percentile. I had to go back and have a core doppler done of the placenta or something & I am still waiting on those results but they want me to go back to the specialist which is hours away from me.. They told me at my 29 week scan the baby was almost 3lbs. Does anyone have experience with this? Could I be put on bed rest or have to deliver early?

I also have bicornunate uterus so limited space which could be the cause..

Just looking for some insight or other peoples experiences!
