Teenage Pregnancy.?

I am 17 and pregnant. My boyfriend and I recently discovered that we have a created a little baby. I am not for along about 5 weeks. At least I think so. My last period was June 5th. I have taken at least 6 pregnancy tests and all positive. I am scared of telling my parents, but also I am scared that I am not ready to be a mother and my boyfriend is excited yet petrified because his family is catholic. I really want to keep this baby, but the more I think about it I dont want to end its life because I was irresponsible. I am just afraid I couldnt care for it the way it needed me too. My boyfriend will be there every step of the way too. I just need to think of what I can really do to decide what to do for my baby. I want him or her to have a great life but I am not sure if I should keep her or give an abortion. = this is caylies friend.
