Weight of baby

Shaquielle • Second time mommy, miltary wife.
I had appointment yesterday my ultrasound tech did. A Growth scan and she said my son is 2 pounds 4 ounces ,but she was concerned because he is at 10 percentile. She doesn't want him to fall below that I wanted to know if has any other moms been told that and had healthy baby because she says he is healthy. BTW I'm 27 weeks and 6 days
