My office wouldn't even try to hear a HB until 12 weeks and even then it took FOREVER b/c Lily kept swimming around.
Until we found out she was a girl we called her "'swimmy" after this painting I have that Ben did when he was 5. There was a fish he named "Swimmy" so we called Lily swimmy b/c she kept swimming away from the doppler, lol.
Its disapointing you didn't get to hear it... but I'm glad everything is A-OK!
