AM I NOT OVULATING OR IS IT THE TEST?

Margarita

Im on cycle day 8 . I started taking ovulation test (DOLLAR STORE ONES) on 9-1 due to my AF STOPPING AND I WAS SPOTTING DARK BROWN so i thought it was over and i got a faint line on both now the strips b keep coming out negative (last month the same) i check my temp yesterday and it was 98.7 , i checked today and its 98.0 im new to the whole temp checking thing as well as the ovulation checking .... Could it be that the tests (ANSWERS OVULATION TEST BOUGHT AT WALMART ) arent working ? am i ovulating?
