Young, want a baby.

Hey guys! I'm so ready to settle down and have a family, but at the same time I know I am not quite ready. I'm only 18 years old, and I know I need to get everything in order and go to school and get a nice paying job, before I should even think about having a child. I just want one so bad. I have a niece and nephew and I practically take care of them, like they're mine. Every time my boyfriend and I have sex, I really wish maybe this time will be the time😂😂 I k ow it's wrong. My bf wants to wait until we're married and older and have our lives basically sorted out but I just can't help my feelings.
