Fitbits can help you keep tabs on lots of things going on in your body—from your heart rate and the amount of calories you're burning, to whether or not you're having a baby.
Wait, what about that last one?
Here's what happened.
When his wife's Fitbit started recording some weird heartrate activity, Redditt user YoungPTone turned to the community boards to find some answers.
"My wifes fitbit is showing her heartbeat being consistently high over the last few days," he wrote in a post entitled HR reading consistently high 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. 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 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."
A bunch of commenters were quick to respond with info about software updates and advice for restarting the device. But then one chimed in with the following response: "Has she experienced anything really stressful in the last few days or is it a possibility she is pregnant?"
Hmmm. Turns out, it was a strong possibilityl "[I] didn't know that would jack up the heart rate," YoungPTone responded. "I might be a dad, YIKES. Now I gotta watch my own heart rate."
For the record, a woman's heart rate increases from the standard 70 to 80 beats per minute to 80 to 90 beats per minute during pregnancy. So if you're TTC, a Fitbit may just be the perfect gift for Valentine's Day!
And of course, YoungPTone came back the next day to announce that he was, indeed, going to be a dad. "I just wanted to say this is indeed real," he wrote in a recent update. "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! Now I'm a regular guy who is preparing to have his first child brought into the world, god willing, in Oct 2016."
Congratulations to the expectant couple!
