I had intercourse with my girlfriend about 4 days ago and was inside her for about five seconds at the most, I did not cum and because of earlier going on of the same day, was dry as far as pre-cum was concerned. However, if I did pre-cum, would like to know could she be pregnant? Also, after all this happened, she took a shower. I know I did not ejaculate inside her, and signs of any cum would have been evident when I pulled out.
