This woman has Fitbit to thank for letting her know she was pregnant

The advent of wearables like the Apple Watch and Fitbit have been godsends for people who enjoy quantifying their lives in steps taken and heartbeats. But could wearable devices be the newest way of tracking serious changes in our bodies?

One woman, half of a couple living in New York City, recently learned that these small devices can go above and beyond what they were designed for after her Fitbit more or less revealed a pregnancy.

David and Ivonne, who asked that BuzzFeed News not share their last names, both started using Fitbits earlier this year in an effort to get healthy. At the same time, they’d been trying to get pregnant for the last few months.

Shortly after she began using her fitness tracker, Ivonne noticed that her heartbeat seemed to be around 110 beats-per-minute, a number just outside the normal range of 60 to 100 beats per minute. Assuming there must be a malfunction with the Fitbit, David turned to people on Reddit’s Fitbit forum to ask if they’d had any experiences with faulty devices.

“My wife’s Fitbit is showing her heartbeat being consistently high over the last few days,” he wrote. “2 days ago, a somewhat normal day, she logged 10 hours in the fat burning zone, which I would think to be impossible based on her activity level…I’m not sure if something is wrong with the sensor.”

David’s fellow Redditors were quick to offer advice, but it was one comment suggesting a possible pregnancy that caught the couple’s attention. Knowing that they’d been trying, Ivonne decided to take a pregnancy test, which came back positive. As it turns out, one of the early symptoms of pregnancy is a spike in body temperature, which in turn ups the heart rate.

David returned to Reddit to share the good news and the response has been overwhelmingly positive, with total strangers wishing the expectant couple the best.

“Thank you all for your overwhelming support,” David wrote in an update. “It’s been awesome to read all the comments and well wishes, even the comments questioning whether I am in fact the father (gotta have a sense of humor on here, right?). I just wanted to say this is indeed real, I do not work for Fitbit, this is not guerrilla marketing. This is real, the fear is real, the excitement is very real! I am a regular guy who was just looking for the communities [sic] help with his wife’s technology issue. Little did I know I got a lot more than I bargained for! Now I’m a regular guy who is preparing to have his first child brought into the world, God willing, in Oct 2016.”
