I went in for a growth ultrasound today (31 weeks 5 days) and my baby is measuring in the 20th percentile for the most part, but the abdominal circumference measurement was in the 5th percentile. I'm going back in two weeks to check the growth, but until then I'm trying not to worry :) I'm still curious though, has this happened to anyone else and how did it turn out? They said my baby looks perfectly healthy otherwise!
