Baby Fitbit: Man Finds Out Wife Is Expecting In Interesting Way

Turns out Fitbits can track more than just your fitness. One man was surprised to learn this when his wife’s tracking device detected a surprise pregnancy.

After noticing some odd heart rate readings on his wife’s Fitbit, David Trinidad posted his concerns on Reddit, thinking there was something wrong with the device. “I'm not sure if something is wrong with the sensor,” he wrote. “Is there a way to reset or recalibrate the device? I'd like to try that before I contact customer service about a possible replacement.”

According to Trinidad, his wife Ivonne’s heart rate was consistently high over the past few days. She had logged 10 hours of activity in Fitbit's “fat burning zone,” but had not increased her activity level.

In response to his post, one Redditor suggested that the increased heart rate could either be due to high stress or pregnancy.

“Pregnancy is a strong possibility,” Trinidad wrote back. “Didn't know that would jack up the heart rate. I might be a dad, YIKES. Now I gotta watch my own heart rate lol.”

The couple then visited a doctor and were surprised to learn that they were expecting. “We’ve been married for a few years now, and one of our plans for 2016 was to hopefully start a family,” Trinidad told Mashable in an email. “But the big surprise was that it happened so soon, and of course, that the Fitbit helped us to figure it out.”

In an interview with Buzzfeed, Dr. Mary Jane Minkin of Yale-New Haven Hospital explained that heart rates can increase significantly while pregnant, but this usually occurs much later. Increased body temperature is a symptom of early pregnancy, as well, which is likely what caused Ivonne’s heart rate to rise.

After discovering the baby news, Trinidad returned to Reddit to share his excitement, and reemphasize that his post was not a ploy to promote Fitbit.

“This is not guerrilla marketing,” the dad-to-be wrote. “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 (we've all been there, right?). Little did I know I got a lot more than I bargained for!”

The couple’s first child is due in October. To share their excitement even further, the two started an Instagram account so people can follow their adventure into parenthood.
