Just want to know !

AF due tomorrow been in pain on and off for past week with my back and stitch like pinching soreness in my abdomen similar to AF cramps but different at the same time :( 
I just either want AF to hurry so the pain stops or an answer but been a year trying and don't want false hope so laying of testing.
Plus I don't chart BT :( and cervix position is everywhere ! Yesterday morning could feel it close thought AF would show (standing up testing) . Last night couldn't feel it was really searching and no luck (sitting down testing) :( . 
This morning couldn't find it laying down next minute just tested sitting down and it's close again . 
Not sure if I should put a pad on . No discharge in undies or wiping . Just creamy CM on finger I test with . 
Do u think AF will come tomorrow or be late ... I just want the pain to stop when it hits only last 10-20 secs and on and off . And I hate wearing pads on AF but wearing them now as I don't know what the hell is happening . I have 31 day cycles due tomorrow
