Dont know what to do.

Hey all, I'm new to this, but getting the hang of things, anyway...I'm pretty regular when it comes to getting my period, the week before i get real bad cramps, cranky the whole deal. Last month November 3rd AF showed up lasted only 4 days...I was due again today however she's not here. I also never got my regular period cramps last week, however I have been extremely tired, nautious, and actually got sick on sunday. CM has been crazy amounts the past week... My back hurts constantly and headaches almost all day. Tempted to test but I have a feeling it will be negative and AF will show up late bc of stress over my job and Christmas 😕 should I wait until next week, or just go for it and test??
