Implantation bleeding or AF

I've heard everyone is different but I want to share my experience and get your advice.

Day 1, roughly dpo 13- a little pink mixed in with cm when I wipe, through out the day.

About two days later, a week before expected AF, I started bleeding. It started out pinkish & dark red mixed with cm, but I wore a tampon.

It lasted about 2.5 days, changing my tampon every 5 hours or so.

I typically have a period for 5 days. What's weird is my bleeding was mixed with egg white looking cm.

I normally also have Bad cramping and this time I didn't even know it was there besides the fact I was very emotional.

I was convinced it was my period, do you feel the same?
