Answer
Hi Mike,
I can't tell if her she got her period?  If she did, there is nothing to worry about.  If she didn't get it, you can check a pregnancy test about a week after you had sex and it will show up positive if she is pregnant.  It sounds like you had safe sex, and the condom was intact, so there is probably nothing to worry about.  Maybe she would like to consider a more reliable method of birth control at this time.  You might consider seeing a family planning clinic or family practice doctor to start on birth control pills.  
Good luck to both of you,
Doctor Joan
