hey hun... I had my AF come sat until tonight.. still light, will be gone in the AM. But it was light, and brown with a little red... I was hoping it was implanting too but i would be like 19po or 20 or something and it would of showed i would think... I'm sorry you got a BFN, but to be honest it was probably AF playing with you.. know what i mean... just hang in there hun, theres always next cycle

good luck
