Oura fitness ring signals pregnancy weeks before test

A 34‑year‑old lawyer in central England received an alert from her Oura smart ring indicating a poor health score, elevated heart rate, higher body temperature and reduced heart‑rate variability. Though she felt fine, the app warned that her body was under stress. A week later her menstrual cycle was delayed, and another week later a home pregnancy test returned positive. She said she checked the ring’s data every morning, treating the warnings as a potential life‑or‑death signal.

The experience mirrors reports from dozens of women who claim their wearable fitness trackers—rings, smartwatches or smart clothing—have flagged physiological changes that preceded conventional pregnancy tests. The popularity of such health‑monitoring devices has risen sharply in the United Kingdom, with recent surveys showing a growing share of adults using them to track daily wellbeing.
