Faint line?

Sara

Hello, I’m 3days late and i just took a test. I think i see a line but I’m not sure. And then i’m having like period cramping, for the past 8 days so i was aspecting AF soon. I don’t understand. I have nausea, bit i thought was just a virus or a more like food indigestion. Is having like period cramp normal at the beginning ? I can’t say. Is this a line or i’m just crazy?
