Is it permissible to abort a fetus in the fourth month due to the mother having blood clots, which pose a danger to her life and the life of the fetus?

If the fetus reaches 120 days of age and the soul is breathed into it, then abortion is not permissible unless it poses a certain danger to the mother's life, even if it is malformed. As for before the soul is breathed into it, abortion is forbidden unless there is a permissible excuse, such as the mother suffering from a serious illness that affects her and her pregnancy.
