Grrr Lost, Confused, Happy, And Sad

Soo Im pose to have my Af on the 29th, and no sign of her!! Usually both of my nipples hurts. Rather if im putting on my bra, or even a piece of clothing rubs agasint them. This usually occurs a week before AF arrives. Nope, for the lasf few days nothing. My left nipple is irritated and thats probably because I keep checking to see if anything has changed. I have a cramps every now an then, but not the ones I get when AF is here. I feel like vommiting every now and again, but I nevered actually vommited. I want to test but so tired of getting negatives, Im not sure anymore.
