I bought a Doppler last week which I was 5w3d.I figured it would take forever to get in and the reviews said it would be 8before I could hear the heart beat! But it didn't take no time to arrive and I got to hear the little heart beat at 6w3d. I paid 37$ free shipping and got the Doppler and two packs of preggie pops for morning sickness! It doesn't show the heart rate which I didn't want anyways cause I didn't want any hints on what the gender is😃
