Period due today

Sarah
Period is due today. I have had some
cramps around my pubic bone. I had sore breasts earlier in the week but they disappeared (the soreness, not the breasts). 
So now I'm left waiting....
CM is light and creamy to watery.
I don't want to take a test as I took one 3 days ago with FMU and it was negative. I'm pretty annoyed with myself for giving in and testing but hey!
I feel so miserable and I'm going on holiday next week, so I just want my AF to show up, so it's over and done with for my holiday- or not show up at all. Why are periods so stressful?
