Hello,
The faint line can be due to positive and it may be faintly positive because you may have taken the test early. Pregnancy test kits are basically qualitative kind of test which just tests presence of hCG hormone in the urine of pregnant woman because this hormone is only produced during pregnancy among women. But this pregnancy test depends upon the particular level of hCG in the blood. So sometime it may be possible that it can give you false negative results during early days of pregnancy only because of un- sufficient level of hCG to make test positive. But you check it by performing a second test on following day or within a week and if both clear lines appear then there is chances to have pregnancy and then you consult with your local Gynecologist. You can also go for blood test which will give you more confirmatory diagnosis of presence of hCG and pregnancy.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
I had 2 tests that way and I have a daughter now! Get blood work done!
