If you look at an UNUSED FRER, they have a faint test lines already. I’m starting to think first response is completely unreliable for early detection now. Also, I’m getting faint positives on every single cheapy strip test I ordered on Amazon. No line progression. So I’m beginning to think all false positives/indents. Even with color. I know I’m testing really early but I don’t think I’m pregnant anymore. Today would be about 10 dpo. But that’s usually when I get my obvious positives when I am truly pregnant.
