32w5d growth scan showed abdomen in 96th percentile

Hi mommas! I am a first time mom here & I just had my growth scan this morning at 32w5d. They are estimating my baby weighs 5lb 6 oz (yikes) and his stomach measured in the 96th percentile (everything else was normal) so I have to go back in 4 weeks so they can measure him again and make sure he isn't getting "too big". 

Has this happened to anyone else and baby's belly wound up measuring normal at the next scan? 

If this has happened to anyone else and the baby's abdomen was still measuring larger, what was the course of action?

Thank you in advance! 😊
