Is there any hope?

I am sooooooo worried and stressed out! I went in for my ultrasound today and I was told the machine only picks up at 6 weeks and I am very early. She said a baby was in there and my gestational sac was in the correct place. Thing is, the doctor told me there was no heartbeat and it could be because I'm too early for the machine to pick up or there couldn't actually be one. So I'm scheduled to go back next week. But the Pierson who performed the sono told me it's nothing to worry about and when I come back it's going to look so different. I am just so concerned and worried it's driving me crazy. I just wanted to cry when I got the news. Has this happened to anyone else?
