Oh damm!!!

Hi ladies, im liz, ttcbby#1 i have read about implantation and read your guys feedback on some post about implantation bleeding. Well AF IS due on the 15th,SHE BETTER NOT SHOW, well i have been peeing alot lately, cramping, itchy nipples, feet hurt like if i have been walking for miles, headches, and about a week ago fever. Well when i pee i do not notice any blood or discharge that can be " implantation bleeding", but when im about to flush a notice little light red or red tissue as if its period blood but very very i mean very light??!! Anyone know what it could be?
