A little concerned...

I went for my first appointment yesterday. And I am DEFINITELY pregnant. They called me back and my blood work said that my HCG levels were at 51,300 and I'm only 6w6d today. Is that normal? She said my levels were "very good" but I was pissed because she took over 2 and a half hours to call me back and it made me nervous cause I had called twice to find out and ughhhh. If I wasn't impatient before pregnancy now I'm even worse lol. Anyone else have levels that high so early?
