On friday of last weekend my girlfriend and I had unprotected sex(no condom, no birth control)....Kind of. I was inside of her for maybe 3 sec(i'm not lying, very short). I pulled out before I climaxed, and about the time I realized the seriousness of the situation. Me and my girlfriend are virgins(i don't know wether what we did would be considered "sex") I did a lot of research and found that the preejaculatory fluid can contain sperm depending on the last time you had ejaculated. I ejaculated the morning of and the night beofre this inccident. After we had done that I was nervous so on tuesday me and my girlfriend went and got an emergency contraceptive, which she took(about 100 hr after we had unprotected sex, I was told they work up to 120hr after). I am still stressed out! I have about 10 days till her period and I don't think I can wait that long. I just wanted some opinions on how much of a chance I actually have. Have ec's ever not worked for someone here? Thanks
