The bleeding could have been implantation blood.
A faint line is still positive. You're pregnant. Call your doctor and make your first prenatal appointment. My first test was a faint line too, so I went out and bought the digital one, which clearly told me I was PREGNANT, lol.
My first test was a faint line and my 2 others I took were pretty faint.
Try taking another one with your 1st morning pee (sorry if that sounds kind of gross) but it is the best time to test because if you are pregnant you will have the highest concentration of pregnancy hormones. That's what my OB recommends when you are trying to figure out if you are pregnant really early in your pregnancy. Good luck!
What was the first day of your last cycle?
A faint line is a line. :)
