Is it permissible for a married woman who has no children and has undergone an organ transplant to become pregnant, given that doctors fear a deterioration of her health or that the fetus may suffer from developmental delays, while there is a possibility that the pregnancy and delivery may proceed without complications? And would she be considered sinful if something undesirable happened to her?

A woman's pregnancy and childbirth are fraught with hardship and danger. Jurists have likened the state of a woman in labor to life-threatening illnesses. However, what the questioner mentioned regarding the possibility of her being harmed or the fetus being deformed does not necessitate prohibiting her from conceiving. Therefore, there is no harm in her proceeding with it, and if anything afflicts her after pregnancy, there is no sin upon her.
