- Ravika, 34, a solicitor from the West Midlands, learned she was pregnant through her Oura ring flagging elevated heart rate, elevated body temperature and dropped HRV — a week before testing positive; she ultimately miscarried after a 'significant strain' notification
- Sofia, 32, spotted two miscarriages in her Oura ring temperature data before carrying her now five-month-old son, and removed the ring for the entire first trimester due to anxiety about checking the numbers
- Oura leads the smart ring market, competing with India-based Ultrahuman and Hong Kong-based RingConn; YouGov found 36% of British adults owned a fitness tracker by January 2026, nearly double the July 2019 figure
- Dr Stuart Lavery, consultant in reproductive medicine at University College Hospital London, warned 'we might be running before we can walk' and said reliability data is lacking, risking 'skyrocketing' anxiety for users
- Dr Chris Curry, Oura's clinical director of women's health, told BBC News the ring is 'a support tool, not a replacement for your care team' and encouraged overwhelmed users to take breaks from the app
Why it matters: With 36% of British adults now using fitness trackers — nearly double 2019's figure — women are increasingly relying on consumer wearables for medical interpretation of pregnancy. Doctors warn the temperature data, never validated for detecting miscarriages, is fueling anxiety and premature emotional decisions about viable pregnancies.
