Hi Ashley
You'll need to speak with someone in Oklahoma - do you have a teacher you can speak with?
One thing I will caution you about - you're still a minor under US law and may be restricted in your choices because of this. Further, you say you're 16 - did you fall pregnant before your 16th birthday? If so your boyfriend could in theory be charged under Oklahoma law with statutory rape. Usually this happens after a parent complains, so you may want to think about keeping them onside.
You really should try to speak with a counsellor/teacher - I'm not going to put you under pressure but that age gap has put a lot of legal and emotional challenges ahead of you. Regardless of what happens, keep your family - they'll usually be the one constant comfort in your life, and you will need their support.
Good luck...
