pregnancy bleeding

Hey ladies, I'm in desperate need of help right now! The other day when we took a test, it said positive, with a very faint line, then disappeared, I started bleeding yesterday morning with no cramps, or clots. I haven't had any sign of a period. I'm not due for another week, well, yesterday, the blood was really pink with a brown tint, & today it's reddish pink, and it's a little heavier. I am very sensitive, but no cramps, or the bowel movements that come with AF, but we are ttc, & I thought it was implantation bleeding, any advice?
