What must she do regarding making up approximately eighty days of Ramadan fasting that she missed due to pregnancy, breastfeeding, and menses, especially since the circumstances that prevent her from fasting persist now and in the future, and is there a specific legal ruling for a case like hers?

A woman must break her fast if she has a valid excuse, such as pregnancy, breastfeeding, menstruation, or illness. She must then make up the days she missed after the excuse is no longer present. The obligation to make up the fasts does not fall away, nor does it transition to feeding the poor, no matter how many days need to be made up. It is not a condition that these make-up fasts be consecutive.
