A little less than a month ago my girlfriend and I were messing around. She was giving me a HJ and managed to make me ejaculate. I got a little bit on her hand but she wiped it off on her shirt and jeans. She said that her hand felt dry after that. About 5-10 minutes later she went inside her pants. What are the chances of her getting pregnant from this? I know that sperm doesn't immediately die when in contact with air, but how long does it live? We were outside and it was cold. Could that change the amount of time it lives? Also, her period was due two days ago and she has yet to have it. This idea of pregnancy came up and got both of us extremely worried. She doesn't feel any symptoms of pregnancy.
