Week by Week Pregnancy Overview
Pregnancy is divided into three trimesters across 40 weeks, with full term considered anywhere from 37 to 42 weeks. Each week of pregnancy brings measurable changes in both your baby’s development and your body. This week-by-week due date calculator helps you find your EDD when you know your current gestational week — useful if you’ve recently had a scan that told you your gestational age but you’re not sure of your LMP.
