Dad-to-be: learned wife was pregnant from Fitbit

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?). "
