Bought doppler when I knew I shouldnt..

🙈🙉🙊 • Mom to 2 amazing little boys.
I got a sonoline b doppler about 3 days ago and can't find my baby's heart beat. I find a strong one and the doppler says it's 120 beats per minute but it's no were Close and it's obviously my own. I should have never bought it. Now I'll stress another 2 weeks until my appt. Awesome.
