I read your question and I think that you need to wait! If you want to be a TEEN mom then at least wait til you are about 17 or 18!
My sister's friend was 15 when she got pregnant but she did it for attention and that still didn't work! It ruined her bladder! She couldn't go to college! She dropped out of High School! She also did it so her boyfriend would stay with her, but he ended up leaving her!
She couldn't go to school unless somebody was able to watch her kid! And she didn't get a job until she was 22 and she ended up living with her mom her told her that she was going to regret this and she did!

Maybe you have watched Juno to many times!
