    length of time since the mother's last menstrual period

    Gestational Age (GA) refers to the length of time a fetus has been developing in the womb, typically measured from the first day of the mother's last menstrual period (LMP). It is used to assess the growth and development of the fetus and to estimate the due date, with a full-term pregnancy usually lasting about 40 weeks.
