Hey guys. We just had sex today with a condom on and I foolishly quickly pulled it off when I thought I was close to ejaculating and after that I saw what looked like either mine or her pre-cum/vaginal discharge about an inch away from her vagina, toward her left leg. There didn't appear to be any other liquid around it and she should be having her period within a week. Is this nothing to worry about or should we consider Plan B?
