19 and Pregnant

Hello ladies, so I am new to this whole thing, my boyfriend actually found it to help me out and try to find people who I can talk to. Anyway onto the story! So I am currently 6 weeks pregnant, and have not told my parents yet. This is where it gets tricky...my parents absolutely hate my boyfriend. So much that they have wanted me to break up with him since we first started dating. My entire family hates him. We have been dating for a year and two months now, but we know we are keeping our child and will do everything in our power to supply a great life for him/her. I am also currently a college student and only work part time (thankfully he works full time). All in all, how am I supposed to tell them? My dad will literally kill my boyfriend when he finds out. I am just so nervous to tell them and am afraid my mom will cut me off her insurance and everything. Please help
