You require help.
Lots of it.
First of all, your boyfriend is a jerk. The years between 21 and 16 are really big ones. It's not a big deal when you're 35 and 30, but 21 and 16 is a HUGE gap. He should have never dated you in the first place. He's going to go to jail soon, too.
Second, your parents are jerks for not telling you about birth control. If you're sexually active, you should have been taking the Pill or using condoms.
Next, you're too young to have a kid. Obviously, you don't have a job, so you don't have health benefits or unemployment insurance. I guess you'll be on welfare. That's a wonderful bit of parenting there, and it's great that your kid will have such great role models to look up to. I'm also assuming here that you are dropping out of high school.
Now you've got child protection services involved. They're there for YOU. You're a child (you are - you're not old enough to vote, drink, smoke, enlist, or drive.) and you've been neglected by your family, abused by your boyfriend, and stuck in a horrible situation.
I recommend an abortion (or adoption), counseling, and a return to high school. Get a prescription for the pill and take it.
Only with parents permission or if she is emancipated.
Yes, you can if you are both emancipated minors. You would have to check your local laws regarding emancipation.
NO but it would help if you did anyways
No.
Not unless you get emancipated (the pregnancy don't do that) or married.
No, not in any state are you emancipated because you are pregnant or had a baby.
Only with parental consent unless she has been emancipated by the court.
No, if possible your boyfriend (as the father) needs to be involved in bringing up the baby.
No
Possibly. In this case, it doesn't appear that the child is "emancipated."
Being pregnant does not change one's age. Until you are an adult, you are not emancipated.
No!
