I agree, all the hpt say even a very very faint line is a positive.
I did two tests with my first pregnancy, 1 about lunchtime, and 1 the same evening both positive - when I went to the doctor to confirm it the next day, like the test instructs you to do, she looked at me like I had two heads.
Aparently, tests are so reliable now, that theres no real need to confirm positive results any more.
This time, once I got two positives, I didn't bother. I just went to the doctor when it was time to get all the 1st trimester blood tests done.
