`Iddah for a woman in case of false pregnancy

Q: Eight months ago, signs of pregnancy appeared on a forty-five-year-old woman. The doctor said that it was a false pregnancy. She has been observing `Iddah (woman's prescribed waiting period after divorce or widowhood) for six months. Is she allowed to end her `Iddah? Is she permitted to respond to the doctor's request to perform a surgical operation of cleaning the uterus?

A: If the reality is as mentioned, this woman's `Iddah ends after the expiry of four months and ten days following the death of her husband. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
