Period 2 weeks too late! Could she be pregnant?

You do not need to inside her to get her pregnant because the pre sperm is just as good as doing it inside her. Spermicidal condoms should kill off the sperm and stress can make your period late. If you did chose to get a pregnancy test you can buy one for $10-$15 bucks just about anywhere and you can know in 3 minutes, or you can wait but it sounds like she is pregnant.
