Possibility of pregnant or mind games

Madison
So yesterday I toon a preg test non digital and I got the faintest of blue lines... This morning I room a digital and it said not pregnant (not one that tells you weeks) 
I'm pretty sure I have implantation bleeding, I get nauscious at night for the past 4 nights, heartburn and headaches. And cold like symptoms for almost a week now. 
My period isn't for another week, so I know theoretically it is too early to test... 
What do you think ladies! I got use some good news :)
