Pregnancy Details
This tool provides instant insights into:
- How many weeks pregnant you are

Instead of manually calculating dates or relying on guesswork, this calculator uses standard medical pregnancy timelines to give quick and reliable estimates. It is especially useful for early pregnancy tracking and prenatal planning.
What Is a Pregnancy Calculator?
A pregnancy calculator is a digital tool that estimates key pregnancy milestones based on your LMP (Last Menstrual Period). Doctors commonly use LMP as a starting point because it provides a standardized way to measure pregnancy progression.
The Babylist Pregnancy Calculator uses a widely accepted 280-day pregnancy cycle (40 weeks) to calculate:
- Gestational age (weeks pregnant)
- Trimester stage
- Estimated due date (EDD)
- Conception window
This makes it easier for expecting parents to understand their pregnancy journey without needing medical calculations.
