No heartbeat on week 9 day 6. What do I do? As my wife just went on a check up today. ?

Sorry to hear about the sad news. Unfortunately, if there's no heartbeat detected they may or may not request for you to come back to check for follow up. If the answer +ve no heartbeat, meaning youve lost your little one. Nothing can be done, as not all foetus survive at early stage. They cant be saved at a the very early stage of pregnancy sadly.
