Not sure. – Pregnancy Sonic | Hear Fetal Baby Heart Beat Review

Okay so this may sound crazy but it may work guys. So I put the mic up to my heart and it showed a steady beat of my pulse (I felt my pulse while looking and listening) (not like if it were on the wall) I am 9 weeks so it's would be hard to hear and I didn't hear much, but I could of sworn I heard something like how I heard my heart rate. It's free, at least give it a try haha.
