Am i pregnant????

Hey ladies so im 13 days late on my period! my boyfriend and i usually dont have sex with a condom. My boyfriend likes to point out that the area around my nipples are larger and darker, ive been nauseous but not throwing up, im growingly tired all the time lately, but those are really the only symptoms i have had. Im scared and excited at the same time! What do you ladies think? Im waiting till Feb. 1st to take a test just in case it pops up out of nowhere!
