My girlfriend and I had protected sex 3 weeks ago. I used a condom and didn't "finish" while having sex. I'm guessing only a small amount of precum came because we didn't have sex that long. Since this incident, she has had her period and hasn't complained of any odd symptoms. Her period lasted 6 days and she said it was a normal period. I'm quite confident she isn't pregnant, but I'm just here for some reassurance I guess, and because I love my girlfriend so much and care about her. Let me know what you think. Much appreciated. :-D
