confused

Denise
So I'm 4 days late from my period then predicted by glow. I've taken two cheap online tests and both clear negatives. I'm not a typical 28 day cycle but this is now 37days. I'm feeling crampy as if my period is coming but my boobs aren't sore or tender and they usually are when I'm due. I'm sooooo confused x any suggestions? Is it wishful thinking?
