First Appointment

I had a Stillbirth at 24 weeks. I didn't know the baby was gone until I went into the Drs and they tried to find the heartbeat. I am now 8 weeks prego and my first appointment isn't till 10 weeks and I am terrified of the Drs office and the same situation happening. Has anyone found anything to be helpful to get through appointments or ask the dr to do something special if they can't find the heartbeat?
