8/9/15 when I wiped myself I notice a pinking dot , ( almost as if my period was starting up ) then the second time I used the bathroom it was a light brown , & then it turned into a darker brown .. again , ONLY when I wiped myself ! in addition my period was 7/11/15-7/15/15 soo that's five complete days . I've been on two forms of birth control , the shot when I was 16 for a year & then the pills for a week . my periods are irregular !! I've been having back pains & dreams of positive home pregnancy tests , could I have experience implantation bleeding OR is this all in my head !!?
