This is what happened,
About a month or so ago (for crazy reasons I can't explain I did something bad. I think I had pre-cum on my finger. But not alot. You couldn't even see it.I stuck my finger up my sisters butt. Then I moved down to her vagina

. She had her hand on it. I think I touched the lower area of the mouth. But not the mouth. Then she took a shower. She had her period afterwards for 7 days. Shes not sick or anything but she has been bieng nice and not a bitch like usuall. I'm 14 and she's 12.
I believe this happened because My meds have been making me act unusual. Also I was in a sort of blacked out phase. Could she be pregnant?????
