Show results clearly:
A tool that estimates your baby’s expected arrival date based on your last menstrual period (LMP), conception date, or ultrasound measurements using validated medical methods.
A mobile application that allows expecting parents to calculate the due date, track gestational age, and monitor pregnancy progress, available at no cost.
A free online calculator that provides an estimated due date, pregnancy week, and trimester progress for expecting mothers.
Uses blood tests like hCG levels or other prenatal tests in combination with LMP to approximate the due date more accurately.
Explains the principles behind estimating a due date, typically using the first day of LMP, cycle length, and standard gestation duration of 280 days (40 weeks).
Adjusts the due date estimate based on your menstrual cycle length, accommodating cycles longer or shorter than the standard 28 days.
Determines the due date based on fetal measurements obtained via ultrasound, providing a precise estimate, especially when LMP is uncertain.
A visual chart or pregnancy wheel that maps LMP, conception, and gestational weeks to help estimate due dates easily.
An online tool available at no cost to calculate your baby’s expected arrival date and track pregnancy milestones.
Explains different methods for estimating due dates:
Provides an estimated “exact” due date based on LMP, cycle length, or ultrasound, though all are still estimates.
A web-based calculator accessible from any device to calculate due date, gestational age, and trimester progress without downloads.
Standard formulas like Naegele’s Rule:
Step-by-step instructions for entering LMP, cycle length, or conception date, interpreting the estimated due date, and tracking pregnancy progress week by week.
