I guess I can't really (or any of us really) can make this decision for you. I know that you're young and you're scared. Things like this happen everyday (several times a day...).
You have options. You can get jobs now, get healthcare, and get ready to be parents. You can terminate the pregnancy and be much more careful in the future. You could also continue the pregnancy and give the baby up for adoption.
I don't know your living situation, other than I think you've stated that you live with your parents still... My parents were not supportive of me when I was pregnant with my son (but I was 16). Eventually they "came around", but I did get married and had a job and health insurance.
Good luck in your decision.
Hugs to you.
