AF due the 24th......

& I have bad lower back pain, bloating/cramping, had cramping to cause me to have diarreah the other night, headache, & always tired. Really hoping its my month... have taken a HPT but it was a BFN. Maybe I am too early? Anyone else having the same thing going on and due around the same time? Suggestions when I should take a test... would this weekend be ok?
