I’m really glad you told your mom about what happened. What your friend’s brother did to you is not ok, and I just want you to know that you are not guilty or responsible for his actions. This was not something that you brought on yourself. I would like to encourage you to report this to police. Your friend’s brother has committed a crime and most likely he will do this again to you or some one else if there is no intervention.
A good indication of pregnancy is to take a pregnancy test. Here is a link to a website that can run a free and confidential pregnancy test for you: http://www.optionline.org/ or you can call 1-800-712-HELP. At the website all you have to do is type in your zip code and a list of centers will appear. Just call the center and tell them that you need a free pregnancy test run. They will be happy to help you.
