Period or pregnancy

Okay so I had sex everyday or every second day threw my cycle this month. I'm 3 days away from my period. And about 2 weeks ago my boobs were sore & larger & they have been like that till this day! I've also had bad cramping on and off. And it tends too hurt while prior to sex too. I took a test on Monday. Which I shouldn't have the girls just wanted me too! And it came out negative! Should I wait and see if my period comes. Or take a test. Is it normal too be cramping 1 week before period? And feeling nausea and pimples! And also tired. These are signs of period or pregnancy ? What should I do....
