Am I losing the baby?

Hi everyone!

I am flying out tonight to go visit my family. I really want to tell them I'm pregnant, but my doctor hasn't gotten back to me. On Tuesday night a had a very faint line on a fairhaven strip. Thursday night a had blood work done and today the lab told me the result is 26.6. I believe that means pregnant, but I'm worried that the level should be higher by now if I already had enough Tuesday night to be detected around 20? =(

Thoughts? Thanks in advance!
