ok, so i know i already posted about my period, but its 3 days late, and i was just wondering if that for whatever reason its late can make it just skip the month or will it start when i stop worrying about it?becuase every morning i feel like its going to start but it never does, and about a month ago i let my b.f rub his penis on my asshole (cuz he likes that) but we never had real sex ever, and he didnt cum near me at all, so we have ruled out me being pregnant from that,... even though it could be possible in some freaky way, but i can feel my period and i keep freaking out about me doing that one thing once, when i have never had sex and i know people having undprotected sex and never getting pregnat and it seems unfair that i would from this, so am i freaking out too much or should i buy a pregnancy test just to see, because in no way at all would i be ready to have one...i mean i havent even had sex!
