Blood Test?

Anyone have a pregnancy test done at a walk-in clinic? I had a faint line yesterday (10dpo) and my mind has been nonstop so I mustered up courage to go. $30 copay, no too bad I guess. Just sitting here at PatientFirst waiting for the results. 
The tech said their test can detect pregnancy within two days of when the fertilized egg begins to divide cells. Her verbage not mine. Lol. 
Wish me luck!
