Try not to worry too much. This has happened in both my pregnancies and both my boys were fine. I had to have scans every 2wks from 30wks to check their progress and they were doing just fine, just slow growers.

Kameron was born @ 6lb at 37wks 6 days (induced as they were expecting him to only be 4lb) and Lachlan was born @ 6lb 7 at 38wks 1 day also induced.
