I dont know why no one wants to answer the question.
If you're living with the chick and not attached in anyway, I wouldn't worry about it. It really isn't any of your business, although the whole situation is pretty funny.
If you are sleeping with this chick, I'd confront her and make sure I wrap up when I sleep with her. (Check for holes also) Some girls are crazy and will screw you over by getting pregnant. Any girl who does something like this only confirms my theory of women being batshit crazy. Hopefully you don't have any friends who are banging this chick.. otherwise give them the bro warning to gtfo.
nah it's not like that stile... been together for awhile, and she wouldn't try to trap me by getting pregnant (y trap a college student making 30k a yr when u make 90 with a real job and u have a trust fund??) and it's mutual/together and all that jazz, just I don't wanna talk about the pink elephant in the room I guess? My best course of action is to just buy another box of pregnancy tests and give them to her and tell her that I noticed she was out of them.
