good question, where in wisconsin are you, better not be anyone i know lol
i know this will sound harsh and mean but if shes 17 why dont you keep it in your pants for a few more monthes and you wont have to worry?
if the doc says the test was neg (im assuming since it was a doc not a preg center thing, it was a blood test) then she isnt, especially if she missed her period already
at 17 it would most likely depend on her parents, the state usualy wont do anything at that age because she is almost 18
sorry i cant be of more help
oh and the only way that would make you a bad person is if you raped her, which it doesnt sound like, you were just irresponsible and didnt think (even if you used protection, you still must have known it could happen and if it did there would be consequences, which makes you irresponcible, sorry but thats that facts)
