Me and my girlfriend who I have been dating for about six months were eating some leftover pizza that i had from last night.  We were watching a movie and next thing i know we are both making out all over eachother.  She took off her pants and i reached into my drawer to find my box of condoms.  I could'nt find any so i looked into the drawer to have a closer look.  All i found was an empty ripped up box.  She asked "did you get it on yet" and i quickly responded with a "ya".  I was having the best sex ever until it was over.  Thats when i turned the lights back on and all i heard was her scream "What the fuck! Where the fuck is your condom".  I just stared at her with a blank dumbass face and responded "Uhhhh i thought you were on the pill".  She immediately started to panic and so did I.  All of my sperm went inside of her and she is on week before her period.  Is there still a chance that she is pregnant please respond.  I am only 19 and i want to go to colledge.
