No sign of AF.

So I was due on on the 13th and I have NO SIGNS OF HER!! AF where tf are you? I've taken 2 tests, both negative on the 14th and 15th. I'm so tired, I'm constipated, got light cramps, headaches, throwing up in my mouth and even a hard stomach. I just want AF so I can start tracking my fertile days again, Do I wait till AF comes or test in a week?
