Possible implantation symptoms or Period?

Wondering what anyone thinks, I’ve been having very light on and off spotting in my discharge for the past 4 days an my period is not due for another 2 days,it’s gone from very faint pink to a pinky brown colour I’ve never ever had spotting for that long before, usually I might notice abit the night before my period actually begins but that’s it! I’m getting low cramps and low backache an these symptoms started 10 dpo, I don’t wanna get my hopes up but do u think this sounds like implantation or just a messed up period playing games with me ? 😬
