Wait or take a test... the eternal debate.

So im about 4 days late for my period which isnt completely out of the norm. More times than not im late. Which is why I absolutely despise taking pregnancy tests. But everything just seems off this cycle. Im not cramping, which I ALWAYS do before my period. Nothing sounds good to eat. And I cant sleep! Omg, I think this is the worst. Im either having horrendous dreams that ive never had before or I just can't get comfortable. This is had been going on for three days. Should I take a test, or just wait a few days to see if my period starts?
