Period or pregnancy ?

My period is suppose to be coming in 2 days but my pms symptoms has not been as strong so I can’t tell if it’s coming or not.

Boobs feel slightly sore (less than usually but does look bigger/nipples doesn’t hurt(

Dull cramps but again less than usual (barley there)

I’ve had headaches for a whole week a few days ago but it stopped. Maybe I was dehydrated?

And dull backaches.

I’m so nervous, I really hope my period comes. It’s just a little confusing. I’ve also been eating a lot and my libido is low which is not like me. Has this happened to anyone?
