I had sex with my girlfriend with a condom. I ejaculated. But then I didn't pee and we had unprotected sex. I didn't ejaculate in her. What are the chances that she is pregnant?
The chances depend upon where she is in her cycle? If she's near ovulation, about 1 chance in 5. That's as high as they get.
By ejaculating then inserting your penis ANY sperm/semen in your urethra (and there was) went right into her vagina.
Wear a condom, always.
