About 3 weeks ago, my boyfriend and I "fooled around" without a condom (his penis touched the outside of my vagina but did not penetrate and he did not cum, but possibly had pre-cum fluid (I do not know). We did not use a condom. My period was suppose to begin a week ago, but it has not started yet. Also, last night the same instance occurred and he penetrated me about halfway with a condom. Is it possible that I am pregnant (especially from the first instance I described)? Also, would you consider the halfway penetration (he was at least in me enough to move back and forth several times and he cummed...pulled out about 2 or 3 seconds later though because I said it hurt too much)? Thanks for your responses...
