Spotting 3 days before period

Bri C
Hey Ladies,
Just looking for advice. I started spitting 3 days before my period with light burning type cramps. The spotting became a bit heavier and then vanished the day my period was due. I've read way too much about implantation bleeding, and read so many different stories that I honestly don't know if that's what is was, or an early period. My cycle is never early and never late... Anyone have any insight or advice? 
Thanks ladies!
