I am so sorry you were raped. If you are pregnant you need to find out as soon as possible. You will need prenatal care if you are, to make sure that the baby and you are okay. The right vitamins and prenatal care is important for both you and the baby if you are pregnant. I know that it is hard to talk to your parents, but they are going to find out one way or the other, so I would suggest letting them know if you are pregnant. You will need their help and support.
