So today I am 13 days late, I've been taking test and nothing but bfn, then today I whiped and their was an enormous amount of CV mixed in with a little pink blood. I've been cramping for 4 days now, and cramping a little today too and this is the first time I see this little pink with CM. I took a test after I saw it, and of course the test didn't work, no lines not even the a control line complete blank, has anyone ever experienced this before with the CM and a little light pink mixed with it? What does that mean, AF coming? Or implantation bleeding, can't test again till tomorrow. Really late now.
