Terms of use

Pregnancy Calculator provides free online calculators and written guides about pregnancy dating, menstrual cycles and fertility estimates. The service is offered as-is and may change or be withdrawn at any time.

All content is for general information. It is not medical advice and does not create any professional relationship between you and us. See the medical disclaimer, which forms part of these terms.

You must not use the calculators as a contraceptive method, as a diagnosis of pregnancy, or as evidence of paternity.

We aim for the calculations to be correct and test them, but we make no warranty that the site will be uninterrupted, error-free or fit for any particular purpose. Estimates are based on average figures and may not match your circumstances.

To the fullest extent permitted by law, we are not liable for any loss or damage arising from your use of, or reliance on, this site or its content. Decisions about your health should be made with a qualified healthcare professional.

Nothing in these terms limits liability that cannot be limited under applicable law.

Please do not attempt to disrupt the site, scrape it at a volume that affects other users, or reproduce substantial parts of the written content without permission. Linking to any page is welcome.

The site contains advertising and may link to third-party sites. We do not control that content and are not responsible for it. Third-party services are governed by their own terms and privacy policies.

These terms may be updated. The date at the top of this page shows when they last changed, and continued use of the site after a change means you accept the updated terms.
