HB in Doppler at 10w1d (surrogate pregnancy)

Whitney • I'm a 30 year old mother of 4 sweet (and incredibly wild) little boys. I am also a gestational surrogate :) #notmybaby
Super excited I managed to pick up a tiny and super fast heart beat on my Sonoline B Doppler. I sent an MP3 to my intended parents so they could listen to it when they wanted. I love this so much!
Anyone else have a Doppler?
