Could it be possible

Kali

So before my period was due I got to faint lines. Then I figured it was false when I started my "period". However it was super light and only laster two days, not enough to fill a pad or tampon. The entire time I never had any of my normal period symptoms. I'm waiting till next week to test but is it possible that I am pregnant. I have had a little bit of nausea and really tired. I also have been unusually hungry. Is it still possible that I am pregnant?
