Once pregnant no, and sadly the birth control shot does not work. It will prevent you from impregnating a woman, but it always fails if you're a woman.You've already been impregnated by Mom
is there anyway to tranform to trans or is it blocked
The best result is either start as a trans, or start as a man, choose the fight the man option, and when the dream comes up to become trans accept it and then never accept the become a female dream.
