I’m just 16 and... I think I’m pregnant. I don’t know what to do.

I don’t know who to tell. I’m scared. I’m only 16. I’m still in high school. I didn’t plan this. I don’t have a boyfriend—just a crush. The school nurse said I should tell my parents… but what if they get mad? What if I get kicked out? What if I ruin everything? I’m so alone. I don’t want to be judged. I don’t want to be labeled. I just want help. Someone. Anyone. Please. What do I do now?
