Advice?

So AF was due today but nothing. At least twice I felt a wetness and thought I'd come on so went to the bathroom to check and it was just pure white creamy cm. 
Not even a hint of spotting or AF. Been cramping quite a bit but she's just not coming. 
HPT this morning was bfn. How long should I wait if AF doesn't show? Not sure what to do next??
