I Got My Period 3 Days Early, Could It Be Implantation Bleeding?

If you got your periods three days early then it is not implantation bleeding because implantation bleeding is not in the form of periods but it is in the form of few spots just for one day. Secondly, not every woman can have implantation bleeding. Only few ladies can get this. Thirdly, this implantation bleeding occurs one week before periods.
