How to tell my parents I'm pregnant?!

Last week I found out I was pregnant, I believe I'm 4 week 6 days (according to the app). I'm 19 years old and yes I do have a job but I stil live with my parents and siblings. I've tried moving out but they won't let me, anyways I've decided to keep my baby! Just afraid to tell my parents/ family because they won't take it well especially on my (ex) boyfriend. Any suggestions?
