Anxiety. So much anxiety.

I was originally told the first appt and u/s would be in Sept but after my HCG numbers came back high they scheduled an early U/S for this Thursday. I keep thinking things are going to be bad. I'm on progesterone. I know I should be all happy and enjoying my time pregnant but the anxiety is making my insomnia horrible. I didn't fall asleep until 6am today. Took unisom tonight so hopefully some rest will come. 
Just needed to vent.
