So, everyone knows cd1 is a major disappointment. Not me. Every month, no matter how detailed/obvious my chart is, I automatically assume I misread my O signs, O'd later, and that my period is the ever so elusive implantation bleeding. Every. Single. Month. It usually takes to the end of day 4-5 for me to start saying, "oh, huh, its still not really letting up. Maybe it IS actually my period."
Anyone else that optimistic/that far in denial? No? me neither.
