Implantation, ovulation bleeding?

So within these past two months I’ve taken a plan B.. which was probably unnecessary but this month I didn’t and I had sex raw he didn’t cum in me but precum still is a thing.. and according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> it was my last day in my fertile window today it’s been 10 days since and Friday I started out with bleeding and my panties were soaked but when I used a pad it was barely blood and barely any when wiping.. but the next day there was blood again until sunday and also I see a little when wiping today.. what do y’all think.. my period is supposed to come on the 28th of this month for December I haven’t had any cramps or sore breast and I also had protected sex on the 18th idk if this could just be the plan b’s catching up to me or what😭
