Global Clinical Standards & Disclaimer

Our pregnancy, fertility, and child growth calculators operate on algorithms derived from global guidelines provided by the World Health Organization (WHO), the CDC, and the American College of Obstetricians and Gynecologists (ACOG). However, these tools are strictly for educational and planning purposes. They must never replace professional medical advice, clinical diagnosis, or treatment protocols from your licensed OB-GYN or pediatrician.

Frequently Asked Questions

How accurate is the Pregnancy Due Date Calculator?
Our globally standardized Due Date Calculator utilizes Naegele's rule, calculating 280 days from the first day of your last menstrual period (LMP). While highly accurate for a 28-day cycle, remember that only about 4-5% of babies are born on their exact due date worldwide.
How does the hCG Doubling Calculator work?
During early pregnancy, human Chorionic Gonadotropin (hCG) levels typically double every 48 to 72 hours. Our clinical-grade tool takes your two blood draw results and the time between them to calculate your exact doubling time, helping identify viable early pregnancies.
Are the pediatric and growth calculators based on global standards?
Yes. Our Child BMI and Baby Growth Percentile tools strictly utilize the official World Health Organization (WHO) international growth standards for infants/toddlers up to 2 years old, and CDC growth charts for older children.
Can I use the Ovulation Calculator if I have irregular cycles or PCOS?
Standard ovulation calculators rely on averages. If you have irregular cycles, our dedicated PCOS Risk & Cycle Analyzer is better suited. We always recommend combining digital tools with physical signs like basal body temperature (BBT) and ovulation predictor kits (OPKs).
