Not sure what's going on here...

So, my period is due tomorrow. Typically a couple of days before my period I get brown spotting (this has been the norm for me for awhile) I also get a couple of bad pimples on my face. It's the sign to say before my period even comes..."I'm not pregnant." I took a digital test a couple of nights ago and it was a negative. I'm not spotting, no acne, but keep getting sharp pains "down there," and some cramps. If you were me would you test again now? Or wait? Also does first morning urine make that much of a difference?
