Angelsounds Doppler

Hi everyone just wanted to say I got the angelsounds fetal Doppler yesterday and it is amazing! At first I couldn't find it but then I rubbed water on my belly and found it right down low it sounds so amazing! Such a fast heart beat! ?? I really recommend this Doppler to anyone who is thinking of buying one! Does anyone know what the average heart beat is per minute for nearly 16 weeks? I'll be 16 weeks on Wednesday! :) ​
