Hundreds of women have noted early pregnancy signs through data collected by wearable fitness trackers, with some devices reportedly indicating changes in physiology before a pregnancy test can confirm conception. These devices track metrics such as resting heart rate, heart rate variability, and body temperature, which can shift with early pregnancy.
Dr. Stuart Lavery, a consultant in reproductive medicine at University College Hospital in London, acknowledged the growing use of such technology. "People are understandably using this technology to try to get a greater understanding, and to try and pick up things as early as possible because it has such a profound impact on your life if you're planning a pregnancy," he said. However, he cautioned that more research is needed to establish the reliability of these readings. "We probably need a lot more data on the reliability, we need a lot more research… otherwise what happens is your levels of anxiety will just skyrocket," Lavery warned.
Dr. Chris Curry, Oura's clinical director of women's health, stated that pregnancy can be an uncertain time regardless of biometric tracking. "With or without biometric tracking, pregnancy can be an uncertain time where many women, particularly those pregnant for the first time, are in the dark about the range of what's normal," she said. Oura encourages users who feel overwhelmed to take a break from the app, noting that the ring is a support tool and not a substitute for professional medical care.
One individual, Ravika, shared her experience of miscarrying after her fitness tracker indicated potential pregnancy. Her experience has led her to reconsider how she will use the tracker if she tries to conceive again. "I didn't really see myself as being an anxious person, but… I think going forward if it came to a point where I had an inkling that I was pregnant and my stats were low, as soon as that positive pregnancy test was there, I do think it would be the best thing for me to take the ring off," she said.
Experts suggest that while these wearables can offer insights, they should be used with caution. The potential for increased anxiety due to misinterpreted or inaccurate data remains a significant concern. The development highlights a growing intersection between personal technology and health monitoring, raising questions about the balance between early detection and psychological well-being.
