Implantation or period?

Has anyone had intermittent mild period like cramps a week before your period is due and gone on to be pregnant?

I’ve been having mild cramps since last night but my period isn’t due for 6 more days. I usually get cramps the day before or day of so maybe it’s just early this month or maybe implantation?

I took a pregnancy test this am and it was negative. I’m 9 dpo today. I don’t remember this happening with my other 2 pregnancies but I randomly fell asleep in the middle of the day yesterday and have had several moments of mild nausea for a few days. Any insight is super helpful.♥️
