35 weeks pregnant got a growth scan done. baby is measuring right but weight wise is small. he only weighs 4 pounds 13 ounces is this bad?

Need more info: Is the 35 weeks gestational age a good number? Were there earlier scans in the first trimester? Was the amniotic fluid amount normal? Does the mother have pregnancy induced hypertension? Does the mother smoke? Most important, was the abdominal circumference measurement done correctly ? Small errors in the abdominal circumference measurement can affect the estimated weight greatly.
