Advice?

Hi so I'm 17 years old and I just recently found out that I'm pregnant.. I want to keep the baby and I'm nervous to tell my family. I'm scared of what people are going to think of me. Any advice? I'm scared, nervous, and don't know what to do. I'm gonna start my senior year in a few weeks and already stressing out. How do I tell the father and my parents? Any advice..
