37 weeks and 17th percentile

I measured small last week so today my doctors gave me an ultrasound to check if everything was okay with the baby. They said the ultrasound was great and he's conpletely healthy but he weighs 5lbs and 6oz. The dr then explained how he is on the smaller side and in the 17th percentile. I was then given a non stress test which they also said was perfect. The dr even said it was great, then said for my next week to have another u/s and nst. I don't understand why I need that done again if everything was perfect just he is small. I weighed 106lbs and 5'6" before pregnancy so I've always been on the small side too. Could that have something to do with this?
