My thirteen year old sister Harmony recently said that she is pregnant. I'm the only person she has told so far and I don't know what to do. She told me she wants to get an abortion, and I understand that. My older sister is 18 and she had Joey when she was sixteen and everything's been super hard for her. We only have our mom and she told me and Harmony that if we got pregnant she would punish us so hard we would feel it for years, and let's just say our mom isn't afraid of physical punishment. Harmony doesn't want to tell our mom and I want to help her out but I'm fifteena nd I don't even have my permit yet. What should I do??
