I know you are scared and do not want to hear a speech on pro-life, but I need to tell you something. Things right now seem scary and overwhelming. I would not rush into getting an abortion because it would be silencing the voice of a human. I would confront your mother or someone you trust and tell them about your concerns. Then you can visit a doctor to confirm you are pregnant. Adoption is such a wonderful option. Open (where you can see your child) or closed (where you don't) are very good alternatives to ending your child's life.
PM if you want to hear more about the adoption option.
