Common question for week 34
What is the difference between early term and full term?
Early term is 37-38 weeks, full term is 39-40. Babies do best when born at 39 weeks or later unless there is a medical reason to deliver earlier.
Every pregnancy is different. Sizes are averages, symptoms vary widely, and none of this replaces the guidance of your own provider.
