Transitioning and baby?

Im 17 and a trans boy. I really want to have a baby and have the experience of giving birth idk if thats weird or not.. but i do.. and i want to start testosterone when i turn 18 or maybe wait until im 19.. and ik i can still get pregnant but if im transitioning id prefer to do all that i can to feel more masculine so i want to have a baby soon but idk im so confused.. i have a boyfriend who loves me but we've only been dating for a month so ik this would be way too soon to talk about.. idk i want a baby so bad it makes me cry to think about not being able to give birth to my child..
