Advice, please!

AF is two days late, and I'm usually very regular. With every period, I have sore boobs which starts a week before AF is due, bad cramps, I'm irritable, etc. This month I have not had any period symptoms at all, which I find weird. My boobs aren't even a little sore. I feel bloated, pressure in my lower abdomen, I've had trouble sleeping, and I've had some back pain. I know that since AF is later I should probably take a pregnancy test just to be sure, but I just don't want to see the negative sign. It bums me out.
