Just like petitewonder and tinkerbell said, you're pregnant. I always seem to get faint positives with my first test.
Try testing again in a couple days and use first morning urine and he line should be darker.
That would mean you are pregnant
it means you are pregnant... a faint line is still positive.. it could just mean that you are early on and your HCG is lower... if you took another test in a couple days to a week, chances are the line would get darker.. but faint line is still positive either way
