Spotting, faint test lines

I took these tests about 2 days ago, since then I’ve taken a blue dye test yesterday that was faint too but a little darker, and then today I woke up and took 2 digitals that came up positive, but I’ve been having spotting, like pink to a little bit of red, I just took 2 cheapy tests and the lines were so faint you can barely even see them, can’t even pick them up on camera. If this is what I think it is I’ll be devastated, this would’ve been our rainbow baby. Any thoughts appreciated.
