Confusedddd

On feb 3rd cd12 .. i had some strange spotting it was light pink with stretchy discharge . That day and the day before i had THE worst cramps .. on feb 6th cd 15 i had stretchy discharge again took an ovulation test and it was negative .. the 7th i took another test and i thought it was positive but the more i look at it i feel like it wasnt positive .. the very next day the 8th it was negative .. idk when i ovulated .. i have a 30 day cycle and was supposed to ovulate the 7th on cd 16.. should i go off that test or should i go off the spotting as ovulation spotting .. i never spot mid-cycle
