Zeinab Sekaanvand was convicted of killing her husband, whom she says beat her for months.
Her execution was postponed after she remarried in prison and conceived a child.
Last month she gave birth to a stillborn baby, putting her at risk of death by hanging as soon as 13 October.
Doctors said the young woman's baby died in her womb two days before she gave birth as a result of the shock she suffered after her friend and cellmate was executed.
