Early symptoms?!

I have only been off bc pill since May 10, 2018 and am suppose to get period Saturday (June 9). I’ve had all my normal period signs, cramping, bloating, but I’ve also experienced dizziness and nausea the past 2 days. Is it possible to have gotten pregnant so soon?! I’m 9dpo and took at test yesterday and it was negative. Is it too early to test? Should I wait til my missed period?

TIA!!
