17 and pregnant. HELP

I'm 17. I took a test and it came back positive. My boyfriend (of over 2years) and I have talked this over. He would stay with me if I had a baby and we'd still be close but he doesn't want to have a baby. I haven't told anyone but him and my best friend. I don't know what to do, both or our parents would kill us. He doesn't want the baby either but he'd help... I don't know what to do, he's in college and I'm graduating highschool next months. What do I do?
