No heartbeat at 8th week

Hi mummies. I dont know what to feel. I just had my 2nd check up and scan via transV and im on my 8th week but no heartbeat has been found. Doc advised to do bloodtest then we can take it from there whether it will push thru or not. Doc said 99% it might be unhealthy. Should i really give up? what do i have to do? Had my blood test scheduled on Tuesday. Pls help i dont know if i should accept it already or not. #pleasehelp
