I have an unprotected sex for 5 minutes with my girlfriend bt I knew that I does not withdraw in her vagina. Even I don't able to withdraw because I had already masturbate at night and I have sex in morning. Bt the thing is that she ovulates after sometimes after having sex. The oval was of white color and the first time that exists. Her last periods first day was on 13 February and I had 15 days after sex. I have sex on 22 February and her cycles duration is 28 days and regular. Please tell me that any chance of her pregnancy? Her periods didn't comes yet. please help. And I am sure there is no withdraw in her vagina.
