Help!!

Before I say anything else please NO HATE! Or rude comments! Please.
Okay so my boyfriend and I are worried that I might be pregnant. I'm 16 I've been on BC for three years, no problem. Last month around Halloween I missed a few pills but didn't think much of it, I've missed pills before. Anyways my period was a no show this month, and my boobs are hurting. I'm almost positive I'm pregnant, since I've never had this before. What should I do? I can't get an abortion because that's just not moral of me. And I'm not the type of person to do that. My boyfriend wasn't really angry or sad or upset at all actually when I told him, he was actually kinda excited. Which made me feel a whole lot better. But where do we go from here?
