Feeling lost..

Is it bad to want a baby so young? Am I too young? To my family I am. I'm going to be 20 this year, & I've been trying to have a baby for almost 7 months now. Actually starting to feel like it's not going to happen 😔 I've told some close family members of mine around the same age & my cousin who's 2 years older is pregnant & im so jealous cuss she knows I've been trying, is it wrong of me to feel that way? I can't tell anyone else . & if they do, like my another close family member told me, that I'm too young & immature this & that . My boyfriend 
Of 4 years has his own place, he works, & I'm looking for a job now since I just stopped going to school . I can take care of a baby, everything will be perfect . It's just my family .
