If my mom was born with all the "girl" chromosomes, then why can't I birth a kid?

If my mom was born with all the "girl" chromosomes, then why can't I birth a kid?#####It’s obviously possible to be born with a vagina and uterus and produce all the eggs, and become a mom and support a baby. <br><br>Why can’t my penis grow a uterus and become a mom? Idk… I just can’t understand biology… <br><br>It should be obvious that I’m joking. I get it’s not biologically possible. I’m just screwing with people.
