Need some help..

Hi 👋🏻 I had a baby in May 2018 and after my cycle was weird and i had a period every month October was the last month I got one 2018 and than outta no where I got a period in July July 22nd is when it started it was normal out of the blue but normal and than this past week tmi.. last Tuesday I had brown stringy discharge? And I had that for 3 days with some brown spots than I had brown and pinkish spots mostly when I wiped and it got more pink but still only when I wiped and then stopped mid day the second day and so the next day (I know too soon) I tested thinking maybe it was implantation? Negative but I know too early lol wat I wanna know is if this could of been my body doing some sort of cleaning? Lol you know or if maybe I ovulated late and this is implantation? Could it even be implantation if it was that long? 🤷🏼‍♀️ Just need someone’s opinion. And is this Friday too early to retest if it was implantation?
