Questions, corrections or feedback. We read everything that arrives.
What to write about
- Corrections. If a date converts wrongly or a chart cell disagrees with a source you trust, tell us which inputs you used and we will check it against our tests.
- Questions about the chart that are not already covered in the FAQ.
- Feedback on the calculator, especially anything confusing or broken on your device.
- Partnerships and press.
What we cannot help with
We cannot give medical advice, interpret scan results, or tell you anything about your actual pregnancy. We are not clinicians. For anything health-related, please speak to your midwife or doctor.
Please also do not send us personal health information; we have no need for it and no way to keep it safely.
