I have a friend who recently told me that she was not a virgin as of last week. She's only fifteen and I'm kind of worried about her. She hinted that they did not use protection and I asked her if her mom knew-no. She told me not to tell anyone else and I really want to talk to my mom but I'm afraid mine will tell hers and she'll get in a whole lot of trouble and hate me. We've been friends for so long and I'm really worried about her. Could she get pregnant? Please help!
