In a thread on Reddit, user YoungPTone was inquiring about reasons that his wife's Fitbit had been showing some unusual heart rate patterns. He said based on her physical activity, the hours she was shown to be in the fat-burning zone seemed impossible. He wanted advice on how to recalibrate the device; instead he got news that will completely recalibrate his life.

Another Reddit user asked if it was possible that his wife was pregnant. Turns out it not only was possible, but that after taking a test based on this thread, they found out that she was indeed pregnant. "I'm going to be a dad!" he posted the next day.

It's such a cute way to be clued in to a potential pregnancy, and much better than, say, puking all day long. But can your heart rate really tell you if you're pregnant?

While no one is suggesting that Fitbit get into the pregnancy game, there definitely is a correlation between heart rate and pregnancy, as a mom's heart has to get more blood to the uterus to support a growing baby. According to experts, cardiac output increases by 30 – 50 percent during pregnancy, and the heart rate increases by 10 to 20 breaths per minute from the average pre-pregnancy heart rate of 70 beats per minute. These changes in heart rate can begin in the first trimester, and while we have no idea how far along in her pregnancy this woman was, it sounds like that Fitbit reading was definitely a clue.

Of course there are plenty of other reasons one's heart rate can increase, which include everything from anxiety to too much caffeine to more serious conditions. So if you find yourself with an elevated heart rate, don't celebrate (or panic) right away. This is just one of a host of possible early pregnancy symptoms women may experience, and every pregnancy is different. The only way to know for sure if you're pregnant is to get confirmation from your doctor or a medical professional, but if you think there's a chance you could be pregnant, and your heart rate is higher than normal, it might be worth it to take a test.
