Me and my gf had sex last nov. 4, 2013 and it was unprotected but we used the withdrawal method. Nov 4 was her first day of ovulation and she has a 35 day cycle.She had her last cycle from oct 21-27. She took 4 ec pills (nordette) at 7:00 pm of the same day to prevent pregnancy. This was followed by another set of pills as instructed which was taken in the morning. After that day, we also had unprotected sex on nov 6,7, and 8. What are her chances of getting pregnant?
