Hey gang. I'm on CD 18 and I'm pretty sure I've already o'ed. I've been pretty dry with just thick white CM. not much. Today when I wiped there was some thick yellow snot like CM. ( Sorry!) it had a tinge of reddish brown. I've never seen this before. DH and I DTD on CD 9 and very late on CD 11. Is this too early for implantation bleeding? Could it be? I'm mildly crampy today. Thanks for responding!
