I am currently 28 weeks but baby is measuring 2 weeks ahead. He is already head down and very low. I had pre term labor signs about a week ago but after a full exam everything is normal. Is anyone else in this or has been in this situation? Due date is Nov 5 but doc says mid October. We have large babies in my family so I expected a big boy, myself and my husband were 9lbs and over 20 inches long.
