Is it weird that I'm a 14 yo desperate for a baby?

I always think in my mind about having my own little baby girl and I always think of names I would want to call her. I don't even consider having a boy I am just always thinking about how badly I want a baby girl to call Sabrina and she be my own. I am not interested in boys or anything I just want to be a single mum really bad but I know I'm too young. Is this weird?
