It was our second time doing it, and the first time, i was afraid i was preg. we did not use a condom, but we only did it for like a min. and now this time, we was in a pool, and no condom again. and last time it turned out i was not preg. well does chlorine do something? could i be preg, he didnt eject in me, im jus freaking out. plz dont say wow your so stupid for not being protected, i kno... but give me your advice pleasee. thanks.
