My gf's regular period due date is 6th or 7th of every month. On 5th night I had unprotected sex with my girlfriend but I ejaculated outside well before I knew I would cumm. However, by the next morning, i.e. by 6th at around 9 AM, she took an Emergency Contraceptive pill (Unwanted 72 - a Levonorgestral 1.5 mg Tab). So today is 8th of May 2015 and she still has not got her periods and it is already 2 days overdue. Is there any chance she might get pregnant even after I ejaculated outside and also took an EC pill within 8 hours from the time we had sex? Please advice, I am really scared as she is 17 and I am 19 years... and we can't go to any doctor either.
Thanks
Sam
