hey, i was having protected sex with my girlfriend and i went to change positions and pulled out. Then i noticed that my condom had broken, i had not yet ejaculated but it was obvious that i had "pre-cummed", we both paniced a little and thought about what we should do, we decided to look online to see what to do and it was not too much help, she washed herself with soap and warm water and then i went to the local pharmacy and bought an emergency something... i cant recall exactly what it's called. im pretty sure that it is referred to as a morning after pill. she took that about two hours after the incident about 6 or 7 hours ago. What i want to know is what the chances are that she will become preagneant and i am also wondering if there is anyhting else i can do?

please help me with factual information,
thanks.
