I've been using my doppler for a few days even though I know it's early. All I've heard is my own. Well, I looked online at tips for finding it and it said to find the maternal artery and listen really closely around it because babies love to hang out next to it. So I did and after searching for about 5 minutes I heard the faint beating of a tiny heart! I had DH come in to confirm. Couldn't hear it long enough to get a heartrate but no denying that sweet sound I love my doppler! It has really helped with my other pregnancies and my worrying.
