5 yrs ago i had a lil girl she was 6 weeks early and weighed 4 lbs 14 oz. im now pregnant again..as it gets closer to the 34th week im increasingly nervous that im going to have him early. ive asked my dr but he said theres not much to worry about. how likely is it that this baby would be early too? i heard theres an increase in the likeliness because i had a premature baby before
