As for the blood test, that's usually very accurate, but you're dealing with human error, just like a pee test. Blood tests can be mixed up, or treated incorrectly, and just like a pee test, they can be taken too soon and show up negative because it's too early to test. Just because you got a negative blood test doesn't mean you're not pregnant.
I am curious, when you went to the doctor did you tell him/her that you had 4 faint positives with a urine test?
