What Is Gestational Age Calculator Dekho?
Gestational age (GA) describes the length of a pregnancy. It is measured in weeks and days, starting from the first day of the mother’s last menstrual period (LMP).
Interestingly, this means gestational age does not start from the actual day of conception. Instead, it assumes conception occurs about two weeks after the LMP, even though this can vary between women.
