Implantation or period SCARE.

I have had bleeding for 4 days or so before my expected period was suppose to start. It was so light and it was like spotting and then went away? So I don't know if that counts as my period for the month of June came or Its implantation bleeding.. I'm thinking its implantation bleeding because my Normal period is 1 week. And is very intense and painful. This was nothing close to it?!..
