Bought a fetal doppler because I haven't been able to see a doctor yet because of insurance reasons, so I bought it for peace of mind !! Well I used it and found a heartbeat and was all excited and come to find out it was just mine, so panic and fear set in & researched and tried and tried and finally I FOUND IT !!!!! I'm 10 weeks and 2 days!! I am over the moon , makes me feel great knowing my rainbow baby is safe and I can go to the doctors not completely in fear!!!!! My husband & son was even more excited that I had to do a few more times!
