Hello, my girlfriend and I recently returned from college for christmas break and had sex using condoms with spermicide. Along with that I pulled out before I went to try to be even more safe about the whole thing, but she is now 4 days late and is worrying about the whole situation. She is having some of her symptoms that her period is going to start but it hasn't. I know stress can delay her period but now I am starting to worry also since it is 4 days past now. Do you think that we should get a pregnancy test or any other suggestions? Thank you
