Answer
Pat,

Every woman's cycle is different and can vary in length from month to month.  Because she did get her period, it is unlikely that she is pregnant.  Using a condom with spermicide also decreases your chances of getting pregnant.  Of course, you can't know for sure until you take a pregnancy test, however, in this situation, it is highly unlikely that a pregnancy has occured.  I hope this helps!
