Our Medical Methodology

Every calculation performed on our platform is grounded in validated obstetric science. While most online calculators rely on a rigid 28-day model, nido incorporates individualized menstrual cycle length adjustments (Naegele's clinical adjustment), correctly aligning follicular phase variations with estimated ovulation and gestational age.

Our Editorial Standards

Our prenatal guides and articles are authored and reviewed by healthcare professionals, including certified midwives, sonographers, and obstetric specialists. We adhere to clinical guidelines established by leading obstetric organizations including ACOG (American College of Obstetricians and Gynecologists), NICE (National Institute for Health and Care Excellence), and SIGO (Società Italiana di Ginecologia e Ostetricia).

Total Privacy Guarantee

We believe reproductive health data is deeply personal. Unlike commercial apps that monetize intimate health logs, nido does not require user accounts, passwords, or tracking cookies. All date calculations run securely and locally in your browser.
