Gestational age refers to the length of time a fetus has been developing in the womb, typically measured in weeks from the first day of the last menstrual period. It is crucial for assessing the growth and health of the fetus, as well as determining the expected due date for delivery. Healthcare providers use gestational age to monitor pregnancy progress and identify any potential complications. Accurate measurement helps in planning appropriate prenatal care and interventions, ensuring the best outcomes for both the mother and the baby. Understanding gestational age is essential for expecting parents and healthcare professionals alike.
