I’m 14 weeks and was listening on the fetal Doppler because I get nervous when I don’t throw up in the morning. Anyway I found the heartbeat...definitely sounded like galloping horses and moved slightly up from the appt along my csection line where it used to be, and it was 149-155 fluctuating. So I know I found it but amidst the typical heartbeat sounds it sounded like someone was sharply tapping with their fingernail on a wall or something like that. Is that worrisome? Anyone have that??
