Terms of Use & Medical Disclaimer

Last updated: October 23, 2026

Medical disclaimer

All calculators and content on ExpectCalc are provided for general informational and educational purposes only. They are not medical advice, diagnosis, or treatment, and they are not a substitute for professional care by a physician, midwife, or other qualified health provider. Calculator outputs are statistical estimates derived from population guidelines and published studies; individual pregnancies vary, and only your own care team can interpret these numbers in the context of your history, examination, and tests.

Never disregard, avoid, or delay obtaining medical advice because of something you read or calculated on this website. If you think you may have a medical emergency, call your local emergency number immediately.

Key limitations to keep in mind: due date estimates carry uncertainty that ranges from days (IVF) to weeks (last period alone); hCG interpretation bands describe populations, not individuals; weight-gain targets are guidelines, not prescriptions. Screening windows mentioned on this site are described for orientation — your provider's dates govern.

Acceptable use

You may use ExpectCalc freely for personal, non-commercial purposes. You may not scrape the site at rates that burden it, republish its content wholesale, or present its outputs as professional medical services. The calculators and content are provided "as is" without warranty of any kind; to the maximum extent permitted by law, the operator is not liable for any decision made in reliance on this site.

Changes

These terms may be updated as the site evolves; the date above reflects the latest revision. Continued use after changes constitutes acceptance.
