Pregnant at 18...

So I just found out that I am pregnant with my boyfriend's baby, and we are both 18. I was so careful, on birth control AND used condoms and it still happened. I have no idea what I'm going to do, I haven't told him yet. When we talked about the possibility, he always made me promise I'd get an abortion, which I always said I would do even before I met him. I feel a little different now that it's happened though. I feel like I am the type of person who would feel really guilty about it. But my family is super religious, like to the point where I am not supposed to have sex before marriage. I know that they would be disappointed in me forever and hate my boyfriend, and that's not an exaggeration. I also know that they would likely make me keep the baby. My mom was adopted and she always wished her birth mom had kept her because she didn't have a great life.

So i have my boyfriend, who would want me to get an abortion, and my parents, who would make me keep it. I don't really want to do either, if it were up to me I would just have the baby and put it up for adoption, I am not ready to be a mom. Please
