My bf and I had unprotected sex, and I am so scared I might be pregnant..?

Did he know you had unprotected sex? If so then he has no business being any more upset about it than you do. It isn't like you tricked him into getting you pregnant. For now you may be over reacting, but if you are pregnant he will have to deal with it just like you. It's not your fault he will have 2 kids that he can't afford. He should have thought of that before he had unprotected sex with you. He already got one girl pregnant, you'd think he would know better. And they will adjust his child support so that he can pay support for both of his kids. But you shouldn't be stressing about his reaction. It isn't like it is your fault if you are pregnant anymore than it is his. And don't let him talk you into abortion or adoption if that isn't what you want to do. He may have another baby, but I'm assuming you don't. Don't let him talk you into making another mistake.
