broken condom! period is a little late. couldi be pregnant?

okay, today its sunday, the 25. I had sex on friday, the 16 and the second time on friday, the 23. The only thing is, the condom broke when i had sex on the 23...im supposed to get my period on the 24-26 and i showed signs of getting it last week like bloated, mood swings, and cravings. i havent gotten my period yet, am i pregnant? or how long should i wait before taking a pregnancy test? is it because of stress that it hasnt come, i have been stressed out a lot lately...what should i do? :(and today, on the 25 i had a tiny bit of colored discharge...it was kind of brown...
