No cool

I was so excited thinking I could hear my babies heart beat. I am 11 weeks. I started at 139 then went to 107 but then I decided to read more reviews and test a few things.
After a nap I put to my wrist and it said 74. Then I put it to my other wrist and it said 101. I know my heart rate didnt increase that much in 2 seconds while laying down.
Waste of $5!!!
