Thick white discharge

About a couple of weeks ago, my boyfriend and I had sex. TMI, but he was without a condom starting out (about 30 seconds, he never came). My period is supposed to come in 2 weeks, but I'm currently experiencing a lot of thick, white discharge. However, I'm not experiencing any other symptoms of PMS or pregnancy (besides moodiness). Does anybody have any advice as to whether or not I could be pregnant?
