Please read this before relying on anything on this site.
This is not medical advice
The content and calculations on IVF Due Date Calculator are provided for general information and educational purposes only. They are not medical advice, diagnosis or treatment, and they must never be used as a substitute for the judgement of a qualified healthcare professional who knows your history.
Estimates, not certainties
A due date is a statistical estimate of when a pregnancy reaches 40 weeks. It is not a prediction of the day your baby will be born, and most babies are not born on their due date. The milestone dates shown by the calculator describe typical windows in a textbook pregnancy; they are not appointments, and your care team will schedule your actual scans and reviews.
Your clinic’s dates take precedence
If the date produced here differs from the date given to you by your fertility clinic, obstetrician or midwife, follow theirs. They have your records, your scan measurements and your clinical history. This site has two values you typed into a form.
No doctor–patient relationship
Using this site, or contacting us through it, does not create a doctor–patient relationship. We cannot and do not provide individual clinical guidance, interpret results, or comment on your treatment.
In an emergency
Never delay seeking medical care, and never disregard advice from a healthcare professional, because of something you have read here. If you have bleeding, severe pain, or any symptom that worries you, contact your clinic or your local emergency service immediately.
Reporting an inaccuracy
If you believe any clinical statement on this site is inaccurate or out of date, please tell us so that it can be corrected.
