The best I can do is offer three steps that can help you...
1. Evaluate your situation honestly, accurately, and with no if's. Are you prepared to be a parent? Can you support your child on your own if he or she was born today? Is the father of your child prepared to help you or are you going to be a single mom? Write down the dream life you want for your child -- include things like stability, love, education... whatever is important to YOU. Then decide if you can provide these things.
2. If you are ready and able to dedicate your life to being a parent, then make a plan. Write it out. Make a budget. Get things prepared as if you have to do this all on your own.
If you are not ready to be a mom, consider your options. Adoption is an opportunity to provide your child with the life you want for them, while being able to keep in touch with the adoptive family and your child. Your parents can even be involved.
3. Sit down with your parents, and begin a serious conversation, informing them of your situation and your plan for the future. You are going to have to make very adult decisions that you may not be ready for, yet they are your decisions.
