Can't sleep until I see a heartbeat

Ever since I found out I was pregnant (5 weeks 4 days,) I cant sleep at all! I am just so scared of going in for my 1st ultrasound at 8 weeks and there being no heartbeat. I cannot wait until that 1st appointment to ease my mind once I know everything is going well. Either way, its all in Gods hands, I just cant help but worry. What was the earlier some of y'all saw a heartbeat? Anybody else in the same boat?
