Well, you first need to see if you are pregnant for sure. So if you miss your period, take a test, and if it comes up positive, you have to tell your parents so you can go to the doctor. I know that you probably don't want to do that, but if you make adult decisions, you have to face adult consequences.
If you are indeed pregnant, your options are to keep it, give it up for adoption, or have an abortion. I don't know the law where you are, but I can guarantee that your parents would have to be involved in any of those three options.
I hope that you've learned something from this. Condoms do break and can be used incorrectly, so if you want to have sex, ask to be put on birth control or use a different secondary method in addition to condoms. (But not pulling out because that doesn't work anyway)
