I think I'm pregnant, what should I do?

well I'm !6 years old and being pregnant isn't an option right now. My family and I are having fincal troubles right now and I can't afford to have a child. I am trying to congrate high school early so I can help my mother and oldest brother with the bills and other things we may need. My boyfriend is only 18 and is flat out broke his mother would never helps us out with a baby because she doesn't like me. and on top of that IF I am pregnant my grandma will kick my family and I out in a heartbeat (yes shes a *****) I strongly don't believe in abortion, If I'm pregnant I would have no clue what to do. this would strongle effect my life and my love ones. so my question is what would YOU do if you where in my sistuation???
