Can you get pregnant from a vibrator?

I dont even knwo why i am doing this but if i dont this girl will drive me crazy! Okay here's the skinny, girl i know only from cl comes up to me at lunch like were best friends and asks me if you can get pregnant from using a vibrator. Normally i would laugh at her but the question took me by such surprise i was dumbstruck. So i tell her no way in hell. But then she tells me that she has two guys who come in her room regularly; her brother and a friend. She thinks one of them found the vibrator and used it, she used it herself sometime in january she tells me and she hasn't had a period since then and has seemed to put on a little bit of weight. she said she is pretty sure she had a period in january. When i told her it doesnt work that way she seemed appeased but came back a week later crying hysterically about it. SO i ask my parents and even the school nurse on her behalf. All getting the same answers. But she still doesn't believe and will continue to drive ME crazy dont know why she thinks i know all this stuff. But anyway, please I am begging you out there. Answer this question based on this and help me get this chick off my back. My sanity rests in your hands :(
