Baby weight and percentile

Jewell
I'm 33 & 4 and had a visit with my OB she told me today that my baby is in the 19th percentile weighing 4lbs 7oz. I have to come back for weekly ultrasounds to monitor her growth. I'm also 1 centimeter dialated which isn't a concern. Btw this is my 4th baby but it has been 6 years lol. My question is has anyone else had these issues arise?
