Frequently Asked Questions

How accurate is the due date?
The calculator provides an estimate based on medical guidelines. Your doctor may adjust the date after an ultrasound.
Do I need to know the exact date of conception?
No — most people use the first day of their last menstrual period (LMP). If you know your conception date, that can be used as well.
What does the trimester information mean?
Pregnancy is divided into three trimesters, each about 12–13 weeks long. The calculator shows you where you are in your journey.
Why does the progress bar show percentages?
The percentage reflects how much of your pregnancy has passed, helping you track progress at a glance.
Can I use this tool for multiple pregnancies?
Absolutely — you can re-enter different LMP or conception dates at any time to calculate new due dates.
