small abdomen?

Jacqueline
So I went to the OB today and they said my baby's abdomen is measuring small... in the 5th percentile, but the rest of her is normal. I am 33w2d and she is 4lbs 2oz. They hooked me up to a non stress test to see if I was having contractions and to monitor her heart rate. They didn't say anything about that so I guess it's normal but they are having me come back weekly for that test and sonograms. Anyone have any experience with this or have any opinions?
