I just bought one of my own!!!! So it worked well for you! I am so paranoid in between appointments i bought it for some reassurance! I bout the same exact one....any complaints or advice on using it?
It worked great! I would definitely recommend watching a few youtube videos. It's hard to distinguish what baby's heart sounds like if you haven't heard one regularly. There are 3 sounds you'll likely hear, a swooshing which is the placenta, a slower beat which is your heart, and a faster beat which is baby. It takes a few tries to find it so don't freak if you don't find it right away! It definitely helped to ease my mind though!
