Too early to test?

AF is due in 4 days. I've been cramping SoMuch this last week.. Very unusual for me; I usually only cramp while ovulating for a day or two, and the day I start AF. 
I took a few tests already last week, way too soon, but too curious not to play lol. I have one left from this batch.. I don't want to intentionally waste it! 
Soooooo impatient!!! ??
