Have a question about our methodology, found an error in our calculator, or want to suggest a topic for the blog? We'd like to hear from you. We read every message and take corrections to our risk model or referenced research seriously.

Because this is a free, anonymous tool with no user accounts, we don't collect or store any information about you when you use the calculator. The most reliable way to reach us is by email. If your message concerns a possible factual or clinical accuracy issue, please include the URL of the page in question and the specific paragraph you're asking about; that helps us route your message to the right person and respond accurately.

What We Can Help With

• Reporting an error in one of our risk estimates, or a citation that should be updated
• Suggestions for blog topics on early pregnancy, recurrent loss, or first-trimester health
• Press, partnership, or research collaboration inquiries
• Reviewer credential verification (our medical reviewer's profile is available on the About Dr. Nair page)

What We Can't Help With

We can't provide individual medical advice, interpret your specific ultrasound or blood test results, or replace a conversation with your OB/GYN or midwife. If you're experiencing concerning symptoms, please contact your healthcare provider directly. For emergencies (heavy bleeding, severe one-sided pain, fever with pelvic pain), go to your nearest emergency department or call your local emergency number.
