High cervix and spotting

Hi everyone I am 12 DPO and my period is supposed to be starting in 2 days. I've been having some light cramping and have noticed that when I check my cervix it is high but there's also some light pink/brownish spotting very light though. Do you guys think that this is implantation or just the start of my period? I can't understand why my cervix would be high though. 🤔
