Miscarriage Calculator FAQs

Common questions about our calculator and methodology

Is the miscarriage risk calculator accurate?

Yes, our miscarriage risk calculator is based on 50+ peer-reviewed studies published in leading medical journals, using data from more than 500,000 pregnancies. It provides statistical risk estimates based on validated research, not medical diagnosis or prediction. Always consult your healthcare provider for medical advice specific to your pregnancy.

Is my pregnancy data private and secure?

Yes. All pregnancy data is encrypted and never shared. You can use the calculator completely anonymously. We do not store personally identifiable information, and nothing is shared with third parties.

What's the difference between free and premium calculator?

The free miscarriage calculator provides a risk estimate using core clinical factors such as gestational age, maternal age, BMI, pregnancy history, and heartbeat detection. The Premium analysis includes all 40+ evidence-based miscarriage risk factors, including additional medical, hormonal, lifestyle, environmental, partner, and exposure factors. It provides the most personalized estimate.

Can this calculator diagnose a miscarriage?

No. This tool provides statistical miscarriage risk estimates only and cannot diagnose or rule out any medical condition. If you experience bleeding, cramping, or concerning pregnancy symptoms, contact your healthcare provider immediately.

What pregnancy weeks does the calculator cover?

The miscarriage risk calculator provides estimates from 4 weeks to 19 weeks 6 days of pregnancy (the clinical definition of early pregnancy loss). It is designed for singleton pregnancies and is not validated for twins or multiples.

How is Pregnalyze different from other miscarriage calculators?

Pregnalyze includes more clinical and lifestyle factors than basic miscarriage risk calculators. It uses 50+ peer-reviewed studies, provides a clear factor breakdown, and offers a research-based estimate tailored to your pregnancy profile. We are transparent about our methodology and limitations.

What do I get with premium assessment?

You receive a comprehensive miscarriage risk assessment analyzing 40+ research-based factors, plus a detailed breakdown showing which factors contributed most to your estimate. You'll also receive an email summary of your results. No ongoing subscription — just a one-time $5.99 payment.

Can I upgrade from FREE to PREMIUM later?

Absolutely. You can calculate your free miscarriage risk estimate first and upgrade anytime to receive the full comprehensive analysis.

Can I get a refund?
