It sounds like you and your bf have been together for a long time. You probably will be together for a while longer too!
Have you considered marriage? I know that you want a child, but marriage is the first step toward a child. You said in your post that a child is what YOU wanted. What do you think your child wants?
If it were me I would want to be born into a family where the mother and father were married. That would be giving your child the best. It would be the right thing to do for him or her.
Ask your parents before you get pregnant. If you do become pregnant, you will need their help and support more than anyone else’s (even more than your boyfriends). Make sure they are on-board first.
Consider the cost of a child as well. You might want to think about having a child after you graduate college and have a stable job that can support a child.
