Baby on the brain

I'm 20 and I want a baby so bad! idk what it is I just do. I crave tiny hands and feet, little toes and fingers. Holding a tiny little person in my arms that came from me and is a part of me. I'm currently with my boyfriend and he says he wants a baby but I know not right now but I do. Sometimes I wonder if I should just get pregnant and offer him a way out lol I know it's horrible but I really want one and at this point I'd do or try anything. How should I distract myself from this feeling??
