You should see a doctor to make sure you didn't have a chemical pregnancy if you had period-like bleeding this early.
I would buy a digital test, that will clearly say pregnant or not pregnant instead of trying to see faint lines. But if you think you saw 2 faint lines and have other symptoms then you most likely are.
If you got two positives, no matter how faint, your most likely pregnant. The bleeding could have just been implantation bleeding. My advice is wait two days and take another test, if the line is any darker make an appointment with an OB/GYN. I wish you the best.
