Gestational age is a term used to describe the age of a pregnancy, typically measured in weeks from the first day of a woman's last menstrual period (LMP) to the current date or the date of delivery. It helps healthcare providers assess fetal development and determine expected due dates. Gestational age is usually divided into three trimesters: 1. **First Trimester:** Weeks 1 to 12 2. **Second Trimester:** Weeks 13 to 26 3.
