What is the ruling on abortion if the gestational sac is attached to an IUD, and there are medical probabilities, knowing that the fetus is five weeks old, and it is most likely that the pregnancy will proceed without problems?

The decision regarding the retention of the IUD is to be referred to specialized doctors. If they determine that there is no harm to the fetus or the mother, then abortion is not permissible. However, if doctors confirm that there is harm to the mother's life that cannot be avoided except by aborting the fetus, then there is no objection to that; because preserving the life of the present mother takes precedence over preserving the uncertain life of the fetus.
