Is this a bad sign?

I found out I am pregnant at 4 weeks, and was exhausted, food averse, and had sore boobs for 4 weeks. During this time I also got sick (fever and sore throat). I've since recovered from being ill, and I'm now 9 weeks. The last ~5 days I have felt...better. In fact, my appetite is back. I feel pretty normal.

My doc won't ultrasound until 12+ weeks (won't even let me make the appointment until next week!). The only appointment I've had was a confirmation, where I just peed in a cup. Nothing else. So I'm worried, and I have no way of knowing if I'm losing this pregnancy or not. What do I do?

What are the chances I'm ok and just lucky my symptoms are a lot better?
