I want to be a mom

i’m only 20. in the past I didn’t want kids but then all of a sudden I got major baby fever but it was always “you’re too young and you’re not ready, are you ready to change diapers” and I agreed. I still agree i’m too young and i’m not trying to get pregnant but I feel like I want to change diapers and just be a mom and carry a baby inside me😭 it makes my heart race just thinking about it.
