Fitness Trackers Predicting Pregnancy Before Symptoms Appear

Ravika, a 34-year-old solicitor from the West Midlands, was among hundreds of women who reported seeing signs of pregnancy on their fitness trackers before they experienced any symptoms. Her Oura ring flagged a poor health score, elevated body temperature, and decreased heart rate variability, which she initially dismissed as unusual. However, after a week of no improvement, she began researching online and discovered a community of women who shared similar experiences.

For women trying to conceive, their fitness trackers have become a lifeline, providing early signs of pregnancy and a sense of control over their reproductive health.

Fitness trackers, particularly those that can monitor body temperature, have become popular among women trying to conceive. A YouGov research in January 2026 found that 36% of British adults owned and used a fitness tracker, with Finnish-US company Oura leading the smart ring market. Women like Ravika and Sofia, who lost two pregnancies before becoming pregnant with her now five-month-old baby son, have found solace in the data provided by their trackers.

The early detection of pregnancy through fitness trackers has sparked a mix of emotions, with some women finding comfort in the data and others becoming obsessed with their stats. As more women turn to their trackers for early signs of pregnancy, it raises questions about the role of technology in reproductive health and the potential for early intervention in pregnancy complications.
