There can be sperm in the fluid before you ejaculate. If she was ovulating, yes, she could be pregnant. She should take a pregnancy test to find out. Then if she's fortunate this time to not be pregnant, you both should be more responsible in the future. I guess this episode might scare you enough, though, without lectures from YA community. Good luck.
Take a test, if it's negative, thank your lucky stars because the pull out method doesn't work. Precome has sperm in it and it only takes one, next time use a condom. If it's positive she can take it from there.
she should take a test, and for further reference, the so called "pull out method" is ineffective, meaning you should wear a condom...its not 100% but it does prevent most pregnancies...good luck!
