possible implantation ?

AJ • x2 🤍👼🏻

i don’t use the bbt method, but I do use opk’s & i know getting a positive opk doesn’t exactly mean you ovulated but I got positive opk’s from 2/25-2/27. Periods due in 3 days but today 3/6 I’ve been spotting brown & I thought my period maybe be coming but I’m still just spotting brown & I put a pad but hardly anything transfers over to it, it’s mostly when I wipe. Could this be possible implantation ?
