Need help dk if prego !?

i had 9 days after my period went off. 8 days after that i had a tiny bit of spotting like the size of skittle. i have been tired lately, way before this week my stomach has been cramping really bad, like PMS cramping. and usually i have this feeling where i think my period about to come down to latter find out it was discharge, but it has become more then common now.. ! I wasted a test this morning and it was negative.. i took it even though my period is due on Saturday.. but maybe there's a chance it would detect i didn't know. but now i know. but what do you all think is the chances of me being prego by these symptoms.... my mind could be playing tricks on me ....!
