Don't know what to do

So me 16 and my boyfriend 17 (turns 18 in June) have been together for almost a year ( our anniversary is May 28). There's several girls my age that are pregnant it's kinda making me want to be but I know we are still super young. My mom keeps making remarks about me getting pregnant in high school and how she thinks I will but she doesn't want me to and stuff like that but there's been several people ask me and him when we are having a baby... I don't know what to do.. I want a baby but we are still so young.. I feel like people are expecting us to get pregnant soon and some are hoping we will... Helppppppppp
