how many weeks is a full term
A pregnancy is not full term until 39 weeks, according to a new set of definitions endorsed by the American Congress of Obstetrics and Gynecologists (ACOG) and the Society for Maternal-Fetal Medicine. This represents an important change from the old understanding under which pregnancy was considered full term from 37 weeks to 42 weeks. The new set of definitions breaks down like this: Early term: 37 weeks to 38 weeks and 6 days. Full term: 39 weeks to 40 weeks and 6 days.
