Pregnancy Details
Pregnancy is a journey filled with excitement, questions, and important milestones. One of the most common concerns for expecting parents is knowing the exact stage of pregnancy and the expected delivery date. This tool removes confusion and provides quick, reliable estimates that can help you plan better and stay informed throughout the journey.

How the Pregnancy Week Calculator Works
This tool uses a medically standard method based on the LMP (Last Menstrual Period). In most pregnancies, doctors also estimate due dates using this same approach.
Here’s what happens behind the scenes:

- It converts days into weeks and months for easy understanding.
- It adds approximately 280 days (40 weeks) to estimate the due date.
This makes the results both practical and aligned with general medical guidelines.
