The pull out method is just an immature, and umprepared individuals excuse for taking precautions. HELL NO!
The pullout method fails more than any other method of birth control, (if you even want to call it that). Stupid move to try it, and maybe this is harsh, but if people are dumb enough to think that they are invincible, and decide to use the pullout method, then end up getting pregnant... I say "you deserve all the shi* you have to deal with. It could have been prevented and it's you own stupidity, and fault for being negligent towards your own future."
Anyway, now that you know how I think of the method.. LOL!
There is a chance she is pregnant, but not as high chance as it would be if you had fully ejaculated. Next time be smart, and put on a rubber. Five minutes out of your life to roll on some latex is a lot smarter than giving up a potential 19 years of your life, and most likely some berating from disapproving family.
I wouldn't sweat it that much. The odds are slim, but hopefully you will take what we say to heart and are a little more careful in the future.
