8 weeks, no heartbeat

Toni
So today at clincical me And the nurse were playing with the Doppler. She told me its old and we may not hear anything. And she couldn't find one. And i got so upset. She told me its too early to hear heartbeat and since I have a lot of fat around my stomach that it could be hard to hear it with an abdominal one. She told me not to worry but I am terrified
