I had a similar situation to the previous poster about the parents...
I was 16 when I got pregnant... My dad didn't talk to me from the minute he found out (on Father's Day no less) until my ex called him letting him know I was in the hospital in labor. My dad didn't even call my mom at work, he rushed to the hospital on his own, and held my hand during my entire labor. When my son was born he was the proudest grandpa in that place...

He and my son have an incredible bond now, he's kinda the son my dad never had (yes, I have a brother but he's not into sports or anything else my dad likes, whereas my son is exactly like my dad).
So, don't be so scared about your parents' reaction... if you're going to keep the baby, they'll come around eventually. Though, it might help if you and your bf both go get jobs (anything, even the "menial" McD's is better than no job), and prove that you're willing to do anything to take care of your baby.
