The length of a human pregnancy can vary naturally by as much as five weeks, according to research published online August 7 in the journal Human Reproduction. Normally, women are given a date for the likely delivery of their baby that is calculated as 280 days after the onset of their last menstrual period.
The average human pregnancy is 40 weeks long. However, a pregnancy is considered term between 37 weeks and 41 weeks 6 days. Babies born on or before 36 weeks 6 days are consider preterm or premature. Babies born between 37 weeks and 38 weeks 6 days are considered early term. Babies born between 39 weeks and 40 weeks 6 days are considered full term.
