Think you might be pregnant? Time to check your Fitbit

Just when you thought that fitness trackers had reached peak creepiness, there's this: a man claims he discovered his wife was pregnant after trying to troubleshoot her Fitbit.

Reddit user YoungPTone logged in to the site to ask fellow Fitbit users about how to fix his wife's activity tracker, which had said she was burning enormous amounts of fat and misreported her heart rate.

"My wife's Fitbit is showing her heartbeat being consistently high over the last few days. 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," wrote YoungPTone.

"Also her calories burned do seem accurate. I would imagine if she was in the fat-burning zone she would burn a ton of calories, so it's not lining up."

Other users of the subreddit r/fitbit chimed in with their solutions, with everything from recent firmware upgrades to stress management and intricate reset buttons being touted as the main suspect for the Fitbit's odd behaviour.

However it was the suggestion by one user, Thatwasunpleasnat, who asked if she was pregnant, that prompted YoungPtone to invest in some home pregnancy tests.

"I might be a dad, YIKES. Now I gotta watch my own heart rate lol," wrote YoungPTone.

It turned out Thatwasunpleasnat's theory was correct, with YoungPTone later confirming "I'm going to be a dad!"

Pregnancy has long been known to increase your heart rate by as much as 50 percent, although for the wife of YoungPTone, this increase may have been caused by the discovery that her husband has been sharing intimate details of their lives with his "internet friends".
