About Pregnancy Due Date Calculator
Calculate your estimated due date (EDD) using four different methods — Last Menstrual Period (LMP), conception date, IVF transfer date, or ultrasound measurements. Our Pregnancy Calculator uses Naegele's rule and medical standards to provide accurate due date estimates.
See your current pregnancy week, trimester progress bar, and key milestone dates including first trimester end, anatomy scan week, full term date, and expected delivery. The week-by-week timeline shows 12 major pregnancy milestones with checkmarks for completed weeks.
Supports IVF pregnancies with Day 3 and Day 5 embryo options, and ultrasound-based calculation when you know gestational age from a scan. All calculations happen in your browser — your health data is never sent to any server.
