Two weeks ago my boyfriend and I were messing around. He had a condom on, and things got more aggressive and at then he stopped and told me that the condom had slipped off his penis, and that his genitalia had rubbed against mine. He promptly replaced the condom with a new one. We used spermicidal condoms, and he did not cum. There was wetness down there, and I am pretty sure this was exclusively from me. The first day of my period was Thursday, and nothing happened, so I took a pregnancy test yesterday and it was negative. I still haven't started my period and I am scared. I am buying another test today. Help!
