My period should come on 8 of this month, and the test is negative

Your testing to early, wait another week if your period still hasn't came and if you still get a negative result then visit your doctor or wait and see if you get a period next month

I do nt have any symptoms of pregnancy, what to do, plzzzzz help me

I just told you in my other answer what to do... its normal to miss a period and even if you were pregnant its unlikely you would have pregnancy symptoms this early on anyway. And according to your other post your only 4-5 days late.
