Important Information

Disclaimer: This calculator provides an estimated due date for general informational purposes only. Pregnancy dating can vary depending on cycle length, ovulation timing, ultrasound findings, and other factors. Your healthcare professional can provide the most accurate assessment of your pregnancy and due date.

An AI Pregnancy Due Date Calculator is an advanced health-tech tool designed to predict your estimated date of delivery (EDD). While traditional calculators simply add 280 days to your last period, an AI-driven tool cross-references multiple personal data points—such as your menstrual cycle history, ovulation patterns, ultrasound biometric markers, or IVF transfer dates—to give you a far more accurate delivery window.

What Makes an AI Calculator Different?

Personalized Cycle Intelligence: Traditional tools assume every woman has a standard 28-day cycle with ovulation on Day 14. An AI calculator adapts to irregular, shorter, or longer cycles.
Discrepancy Reconciliation: If your ultrasound scan date differs from your period-based calculation, the AI analyzes clinical criteria (like Crown-Rump Length) to determine which metric is more reliable.
Probabilistic Arrival Windows: Instead of giving you just one rigid date (since only about 5% of babies arrive on their exact due date), AI predicts a dynamic window showing the highest probability dates for going into labor.
Full Timeline Generation: Automatically maps out key pregnancy checkpoints, including optimal windows for trimester transitions, genetic screenings, and anatomy scans.

How to Use the Tool (Step-by-Step)

1.Select Your Calculation Basis:Choose the entry point that fits your situation best.

Select your primary input method from the available options:

Last Menstrual Period (LMP): Best if you have a predictable cycle.
Exact Conception Date: Ideal if you tracked ovulation via testing kits.
Ultrasound Scan: Most accurate if you’ve already had a early dating scan.
IVF / ART Transfer: For pregnancies conceived through assisted reproductive technology.

2.Enter Your Core Dates & Personal Metrics:Provide your specific timing inputs.

If using LMP: Input the first day of your last period and your typical cycle length (e.g., 26 to 35 days).
If using Ultrasound: Input the date of the scan and the gestational age reported by your doctor (weeks + days).
If using IVF: Input the transfer date and specify whether it was a Day 3 or Day 5 embryo.

3.Run the AI Analysis:Generate your personalized report.

Click Calculate. The AI processes your inputs against clinical dating algorithms to determine your gestational age and estimated delivery date.

4.Review Your Custom Pregnancy Roadmap:Explore your results and timeline.

Review your results, which will typically include:

Your Estimated Due Date (EDD).
Your Current Gestational Age (e.g., 10 weeks, 3 days).
Your Trimester Milestones and recommended windows for prenatal appointments.
