Fitbit Knows You're Pregnant Before You Do

Fitness trackers can keep tabs on some pretty important things: calories burned, sleep patterns, heart rate,  breakups—and now, it seems, conception. When the wife of a Reddit user started experiencing some funky Fitbit activity, he turned to the community boards for some technical help. But the ultimate answer was a bit more biological.

"My wife’s Fitbit is showing her heartbeat being consistently high over the last few days,"Reddit user YoungPTone wrote in his initial post. “Two 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. Also her calories burned do seem accurate. I would imagine if she was in the the fat burning zone she would burn a ton of calories, so its not lining up. I’m not sure if something is wrong with the sensor. 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.”

Several commenters chimed in with feedback about software updates and advice for restarting the device. But user Thatwasunpleasant dove deeper.

“Has she experienced anything really stressful in the last few days or is it a possibility she is pregnant?” the user asked.

“Pregnancy is a strong possibility, [I] didn’t know that would jack up the heart rate. I might be a dad, YIKES. Now I gotta watch my own heart rate,” YoungPTone responded.

Pregnancy certainly does increase your heart rate. Because blood volume increases by 50 percent, more work is required from your heart for circulation. Keep that in mind as you exercise; you’ll want to build in about 15 minutes to cool down.

As for anxious dads-to-be? As YoungPTone will learn, parenting fears can certainly quicken your pulse. “I’m going to be a dad!” he wrote on the thread the next day.

Congratulations to the expectant father! And kudos to Reddit for cracking this case.
