Is 4.8 pounds Normal for 34 weeks?

At my 34 week 4 day ultrasound they said my baby estimated at 4 pounds 8oz. The tech said that was normal and everything looked fine. Now my doctor wants me to get another ultrasound to make sure baby is growing. He’s in the 15 percentile. Everywhere I look it says it’s an average weight baby moves like crazy and kicks extremely hard.

Anyone else experience this?
