Af is due today and no signs she is coming

Af is due today and there are no signs she is coming I feel really blah my stomach is upset and my head hurts and my nose is stuffy and I keep sneezing like crazy. I had a little bit of cramping a few days ago and my cm has been really creamy and lotion like. I feel bloated and I'm not sure what to think.when do you think would be a good time to take a test? Should I wait?
