implantation bleeding??

Emma
So since Tuesday 28th I've had spotting which has been barely there, only when I wipe and is light pink in colour. Had some mild cramps with it too but only lasted 2 and a half days! Tuesday Wednesday and Thursday morning and today (Saturday) I've had no cramps but some brown spotting like I usually get the last day of a period? I took a test Friday not with fmu and had the faintest line ever but sure it was there! Could this be implantation bleeding or am I out this month? AF is due Monday 3rd! So confused 🤷‍♀️ Also I've had two previous pregnancies neither of which I've had any bleeding, is it possible to have implantation bleeding after not having it before?
