Will I Get My Periods Soon As I Have Symptoms?

hi, I had my last period on December 29th, 2010, ending around January 3rd. I've been having pms symptoms(sore breasts etc) for about 5 days now. I was due for my period either yesterday or today. I've been through a lot of stress lately, and I began working out. I'm also sexually active with my boyfriend; he will penetrate me for about five seconds, and then put a condom on. do you think I'll get my period soon?
