STILL SO NERVOUS, but HCG levels increasing!

So, I went to the dr. on 8/1 and had an ultrasound, afterwards my hcg levels were drawn. The doctor called me the next day saying he was concerned because my numbers were so high that he would have expected to see more in the ultrasound. He ordered another hcg test for today and the numbers came back looking really good! I'll be getting another ultrasound tomorrow and I'm hoping that it turns out well and we see more of the baby tomorrow, hopefully even a heartbeat! Does everything look good to you all so far?? I'm so nervous!!
