I am bleeding today which, is 3 days before my period should start, and I want to know is it implanation? - blood in mucus 3 days before period

I do not see a drop of blood in my underwear and when I was wipper red, but there was a lot of mucus mixed with it. Rose and I began to cramp a little. Is this my period? Or implantation bleeding?
