A New York City woman learned she was pregnant after her Fitbit tipped her off to a higher-than-usual heart rate.
The woman's husband posted about the issue last week on Reddit, believing there was something wrong with the workout-tracking device.
Then, he received hundreds of responses and many asked whether his wife was unknowingly pregnant. It turned out she was pregnant.
He updated his post to say: "Thank you all for your overwhelming support! Its 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?). "
