Nervous about ultrasound!

Brittany
My first appointment is tomorrow. Usually they do bloodwork and paperwork and then they will do an ultrasound a few days later. I'm so nervous. This pregnancy doesn't seem real. And I've only taken one pregnancy test which was a very light positive. My fear is that I'm gonna go in and they won't be able to find anything. They will do another pregnancy test tomorrow which will be reassuring. Anyone feel like this?
