I just thought might be helpful for those who are curious of hearings heart beat. It's called "my baby's heartbeat". Recommends for women in their 30-40 weeks but I am 11 an I can hear mine. It's a paid app, but I really like it because I am able to just chk in once an while to hear it an make sure it's still there. It's comforting.. Because I am in still the 1st trimester. Not trying to promote just thought would be helpful for those curious to hear it.
