Of course we've all heard the old wives tale that girl's heartbeats are faster than boys. Have any of you had any experiences that would lead you to believe that there may be a little bit of truth to it? I'm 12w4d & my little peanut's heartbeat is between 160 & 180 on average. I have a pocket fetal doppler that I use to listen morning, evening & night. It's nice to have the reassurance of knowing everything is ok at that moment. It's the sweetest sound in the world. <3
