When Your Friends Are Clueless About Sex/Sexuality http://www.scarleteen.com/forum/Forum2/HTML/000699.html
Your friend says she has had her period twice and the test came up negative. She's not pregnant. You can't have a real period if you are pregnant (there's breakthrough bleeding, but that's noticeably lighter than a period).
You sound like a good friend. Maybe you should print up some articles off the site for her to read. Definitely you shoud read the links I gave you for some ideas. supply her with condoms if you can. Encourage her, tell her you care about her health and well-being.
cheers, hope it works out for both of ya.
