Conception CalculatorReport a Pregnancy Calculator Formula or Date Error
Email hello@conceptioncalculator.org with the page URL, calculation method, non-sensitive sample input, result received, and result expected. A complete example makes it possible to distinguish a formula error from a different dating convention.
Before reporting, check the pregnancy calculation formulas for cycle-day counting, LMP adjustments, ultrasound age, and IVF embryo-age offsets. Do not replace the sample with your own medical record; invented dates are sufficient to reproduce a software issue.
Report an Accessibility or Broken Calculator Page
Include the page, browser and device, the action you attempted, and what happened. Helpful reports identify a label that was unclear, a control that could not be reached by keyboard, text that did not fit, a screen-reader problem, or a calculation state that failed to appear.
Screenshots may help with a visual defect, but remove names, dates, account details, notifications, or other private information before attaching anything. The site does not need personal pregnancy data to investigate interface behavior.
Ask a Privacy or Content Source Question
Privacy questions should identify the relevant statement on the privacy policy. Content-source questions should name the page, heading, and claim so the cited authority and wording can be reviewed efficiently.
We welcome corrections supported by an accessible primary source. A proposed change may require checking the formula, source date, clinical context, and effects on other calculator pages before the website is updated.
Do Not Send Personal Pregnancy or IVF Medical Information
Email is not a secure clinical portal. Do not send names, birth dates, ultrasound files, test results, fertility clinic documents, patient numbers, diagnoses, symptoms, or other information that identifies a person or treatment cycle.
ConceptionCalculator.org cannot provide individualized medical interpretation, establish paternity, or tell you which clinical date is correct. Messages asking for personal medical advice may not receive a substantive answer because the necessary care relationship and records are not available.
Get Professional Help With Pregnancy Dating or Urgent Symptoms
Questions about pain, bleeding, reduced fetal movement, pregnancy viability, test results, prenatal appointments, infertility, medication, conflicting scans, or treatment decisions belong with a qualified healthcare professional. Contact local emergency services for urgent or severe symptoms.
A website correction inbox is not monitored as an emergency service and cannot contact a clinic on your behalf. Use the phone numbers and urgent-care instructions supplied by your care team when time matters.
