First App Tomorrow

I have my first appointment tomorrow. I called when I first tested positive and they scheduled for what I would calculate as 8 weeks exactly. And that is tomorrow. I'm so nervous and anxious that something will be wrong. I'm also really hoping for an ultrasound of some sort but I am in the dark about what the first appointment will consist of. Here's hoping for a positive experience and for my nerves to calm down so I can sleep.
