Light cramping 3 days before period??

Kortnie

So I normally cramp pretty bad the week before my period. Like curl up in a ball bad. I’m 3 days away from when my period should come and I’ve only had slight cramping the past 2 days that only last a few minutes and then it’s gone. And it’s only happened maybe a total of 4 times. Does this just sound like my period is coming or could it possibly be implantation?

I’m not testing until a few days after my missed period if I do in fact miss it.
