HCG level

Aubrey
I had my 5 day transfer 6 days ago. They told me to come for my blood test today but it was a mistake and they really wanted me to come in Friday. That would be 9 dpt. 
Nurse just called and said I am pregnant. But my HCG level was 36. She said at 9dpt level should be 50-100. She said I am pregnant though. Am I? Is there any frame of reference for HCG levels 6dpt? Help! We want to be excited but are cautious.
