Obviously the poster has some more issues than just his sister's possible pregnancy. To the
OP I do not even think she's pregnant. It would have come off mostly in her rear, and if it just barely touched the mouth of her vagina I wouldn't worry. She also had her period and hasnt had anymore symptoms of pregnancy.
Why were you touching your sister's private parts or naked together?! I seriously think you should look into counseling and call your psychiatrist immediately if your medication is giving you black outs ect. Medication isn't an excuse for the behavior although it may have amplified it. How is your sister going to be effected from your touching of her? I completely agree with Jordan/Superstar. Your sister isn't pregnant. But you really need to get some counseling, and so does she. Being afraid b/c of Domestic Violence isn't acceptable either since hitting you or your sister isn't going to solve any issues here. Please try and talk to your psychiatrist/doctor about it b/c not only is your welfare but that of your sister's is also in danger
