Authorship and medical-review disclosure
The byline “WellnessCalcs” identifies the project that publishes and maintains the material. It is not a claim that a named clinician or multidisciplinary medical team reviewed the content.
WellnessCalcs content is not medically reviewed. The project does not diagnose, treat, prescribe, provide prenatal care, or claim clinical expertise. Health-related language is intentionally conservative, and pages identify where professional care is appropriate.
Source priorities
Primary studies and public guidance from organizations such as CDC, NIH, NICE, ACOG, and the Office on Women’s Health are preferred over unsourced summaries. A source is included because it supports the method or context—not because its presence turns an online calculator into medical advice.
Corrections and updates
Meaningful revisions receive a new method-and-sources review date. Styling-only changes do not justify presenting old material as newly reviewed. Report a reproducible concern using the contact form.
