5week ultrasound - what do you guys think?

Lynn
Had our 1st ultrasound today at exactly 5 weeks. Gestational sac and yolk was visible. HCG was 5097 (at 4w+1 it was 467). 
Anyone else have a 5 week ultrasound? How does this compare? Does it seem really blurry? What about HCG?
 I'm excited there was a gestational sac but still nervous. 
Next ultrasound is next Thursday and RE is expecting to see/hear a heartbeat. If everything looks good then he will discharge us to a regular Ob.
