I'm late on my period spotted for a couple of days negative test what's wrong with me

May be an off period, which can happen. Your period may start up as regular, or it may be very light this cycle.

It could also be pregnancy is possible and it just hasn't been picked up yet on a test. Give it another week and see what happens. If a normal period still doesn't show, try another test... be sure to follow the directions exactly. If still negative, wait and see what happens next month when your period would be due and test again if need be.
