Methods
Some countries count gestational age from fertilization instead of LMP. This method of counting is also known as fertilization age, embryonic age, fertilizational age or (intrauterine) developmental (IUD) age. This method is more prevalent in descriptions of prenatal development of the embryo or fetus. The LMP gestational age is usually greater by about two weeks. Also, pregnancy often is defined as beginning with implantation, which happens about three weeks after the LMP (see the beginning of pregnancy controversy).

Famous quotes containing the word methods:
“Parents ought, through their own behavior and the values by which they live, to provide direction for their children. But they need to rid themselves of the idea that there are surefire methods which, when well applied, will produce certain predictable results. Whatever we do with and for our children ought to flow from our understanding of and our feelings for the particular situation and the relation we wish to exist between us and our child.”
—Bruno Bettelheim (20th century)
“A woman might claim to retain some of the child’s faculties, although very limited and defused, simply because she has not been encouraged to learn methods of thought and develop a disciplined mind. As long as education remains largely induction ignorance will retain these advantages over learning and it is time that women impudently put them to work.”
—Germaine Greer (b. 1939)
“I believe in women; and in their right to their own best possibilities in every department of life. I believe that the methods of dress practiced among women are a marked hindrance to the realization of these possibilities, and should be scorned or persuaded out of society.”
—Elizabeth Stuart Phelps (1844–1911)
