Ways to tell Unsupportive Parents you're pregnant?

I know where you're coming from, when I was 16 I was forced into an abortion by my folks cuz they didn't want me 2 have my baby.Either have a close member of your family be there when you tell them or the father of ur baby, someone needs to protect u &ur child. Sit down with them and say "Mom, dad I know you're gonna be upset with me but I'm pregnant, I feel I'm responsible enough to take care of this baby so I'm asking you to support my decision." Once you feel that the situation is going to get ugly get out of there, I know you wouldn't want to call the police on your folks. Good luck to you
