36 week scan

Megan
Went in to see my doc and he told me that the little man is measuring 5lbs 8oz. They are concerned because he is measuring in the 15th percentile and his femur is measuring really short as well. Mind you I am 5'4 and fit as can be. My fiancé is 5'6 and fit as can be. Due date is August 30th. Anyone else experience this and the babe came early or on time and was healthy? Everything was great on the scan. Just a worried mommy. Thank you lovies!!!!
