AF due 10/7-10/8, No Show

Well, AF was due to arrive Tuesday or Wednesday but no real signs of her at all. I don't really have many pregnancy symptoms either (back ache, bloating, and a slight increase in peeing). 
I was pregnant back in June/July and that ended in a mmc, that time my nipples were sore. This month I had sore nipples mid cycle that ended three days later.
​I'm terrified to test because of the disappointment if it's negative. I always have regular periods but I've heard it could take a while for them to get regular after a d&c/mc. This is only my first real cycle after my d&c that was August 6.
​What does everyone think?
