I messed up..Any advice?

I'm a month away from turning sixteen and I just found out I'm pregnant. This came as a complete shock because I've always been the "safe-sex advocate", but I completely forgot about going off of my birth control two months before (I used to get the shot and spaced that I hadn't gotten it). I remembered about a week after the fact, but after reading some things online, I assumed I was fine. Unfortunately that wasn't the case. I want to keep the baby, and so does my boyfriend. My mom (who is the only person i've told, other than my boyfriend) wants us to move in with her. She wasn't really there while i was growing up and my dad raised me, so she said she wants to help me with this as much as she can. If i move in with her, she can get me a job where she works but other than that, i can't get a job. My boyfriend brings home about $150-$200 a week at his job, which i don't think will be enough for a baby. I want to move in with my mom but I'm scared it'll upset my dad. This whole situation is a mess. Anyone have any advice?
