Today at my anatomy scan my baby has only gained 5oz in 3 weeks the doctor is concerned and put me on steroids to promote lung growth just in case he has to come earlier. "IUGR" is anyone going through this or has gone through this I have to go to appointments more often now. What causes this they said it didn't look like it could be any genetic abnormalities could my baby just be a smaller guy. So worried I just hope I can carry my little man to full term
