My girlfriends period is late by about a week. Around the time she normally has her period she spotted which is kinda normal for her but usually her period immediately follows. We have not had unprotected sex I always wear a condom. She is not on any birth control however. Is there a chance she's pregnant? She has been camping on and off and her breast are sore which are usually indications that her period is going to start soon but it hasn't yet. One thing to note is I was looking at the condoms the other day and found out they were expired when I bought them by about 10 months. The condoms never came off or busted when having sex with the expired condoms and we only used about 4 before I realized. I am starting to freak out since her period is so late.
