AF is 8 days late. I did 2 FRERs three days ago and got faint lines within 3 minutes, they also have colour to them making me think they are positive. I then did a CB digital and it said not pregnant. I've since done a blue die sainsburys test and had what looks negative to me. What should I do? What do you think? Surely if AF is this late the lines should be darker and CB digital should say pregnant?
