Plssss ... tel me..
If she took the pills within 72 hours of the event that you described, it is very unlikely that she is pregnant, especially since you did not ejaculate inside her vagina.  It is not uncommon for the morning after pill to cause irregular periods for that cycle until things become normal again, and that is probably why she is having the unusual period.  Her cycles will probably become normal again within the next few weeks, if they don't she should call her doctor.
