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 answer is simple, even if not actually correct. Pregnancies are considered full term at 40 weeks, and many women count four weeks as a month while they are pregnant, making the result a ten month pregnancy. On average there are actually 4.33 weeks in a month, however that a third of a week tends to get lost in the pregnancy shuffle for much of us. Many women also find it easier, when asked how pregnant they are, to answer in weeks instead of months, because pregnancy is generally a count down.
