Me and my girlfriend had intercourse the 5th but she did not have her birth control patch on because her period was the next day. I'm wondering what the chances are of the pre-cum causing pregnancy? I urinated between the last time I ejaculated and the time I we had intercourse which I have read washes out any left over sperm from the last ejaculation leaving little trace or no sperm at all. On top of that she started her period which last four days so I would think if that washes out the egg and helps reduce the risk plus sperm can live for only 3-5 days so by the time she's off her period any left over sperm would most likey be dead? So basically my points are • it was pre cum which has a unlikely possibilty of causing pregnancy • I urinated between ejaculations so that washed out a lot of sperm. • she started her period the next day which last 4 days So how worried should I be? And can I get a accurate result form a pregnancy test if she takes one the day after her period which would be the 10th?
