Getting pregnant at 20 yrs old

I'm going to be 20 in August. I love my boyfriend and we have been together for a year now. My family hates him and my bestfriend. Recently though me and him have been having baby fever. He is 22yrs old. I want one a lot but at the same time I feel like I'll be upset when my friends are going out to party and I can't. I feel like I won't be missing much though if I have something I adore and live for(my child). Any advise? I'm at crossroads.
