I agree with the other ladies! Try to find another doctor! Those tests are not rocket science even to a lay man! Since you have done at least two tests and both show two lines, it is highly unlikely that they will be evap lines. Sounds to me like you are pregnant!

And how dare that doctor start talking about the responsibilities of parenthood - it is your responsibility and choice!
Regarding the test, the positive line may be fainter if you have tested quite early and as the HCG hormone doubles, the line gets stronger. If the line starts to get fainter then disappears totally, it would indicate a chemical pregnancy, which means the pregnancy wasnt meant to be. Therefore, it is important you monitor it and the best way is to get a blood test, as Heyknack said since they can tell you if your HCG levels are normal or not.
