Various things can infulence your fertility cycle, such as stopping birth control recently, so you may find that things can take a while before you develop a pattern.
Also it mean little as to when you finished your AF, but more importantly when did it commenence as that is CD1. A text book cycle is AF starts =CD1, Ov about CD14, LP= 14days then you would either get AF about CD28 or hopefully a BFP.
The bleeding mid cycle could be AF (again) if your coming off BC or possible Ov or implantation.
