Baby Measuring 2 weeks Behind! Should I be worried?

Jessica
My calculations say October 8th. However, with my 34 week 5 day ultrasound baby weighed in at 4lbs 8oz and smaller than the average fetus at that age. Ultrasound Tech saying due date Oct 16th. Dr. Sending me for a stress test this Sunday. It's kind of stressing me out. Ugh
