D&C tmrw

De
Going in for a D&C since finding out thursday at 12 weeks baby had no heartbeat... My 1st visit to obgyn was 8 weeks 6 days and heard healthy heart-rate at 176 and developing on time... Went into genetics testing thursday and they said no heartbeat and no bloodflow, measuring 8 weeks 6 days.  I still feel pregnant and i just cant believe this is the outcome.  I have 3 kids already and never thought id experience the death of my unborn baby.  
My obgyn only called to express his condolences and ask how i wanted to proceed... natural or D&C??  Im uneducated on both so i asked to let me discuss with my SO then i would get back to him.  We decided that since 3 weeks already passed away i may not naturally do it, that we would schedule the procedure.   Why didnt he offer to second opinion this other doctor?  Will they verify at the hospital before they begin??  I dream that its still alive and they take it anyway...
