What is the expiation for a pregnant woman, in her second month, who breaks her fast for the entire Ramadan based on her doctor's request?

If a trustworthy doctor informs you that fasting will cause harm to you or the fetus, then you must break your fast and make up the missed days when it becomes easy for you to do so during the year. If the reason for breaking the fast is solely out of fear for the fetus, then you must make up the missed days and offer a fidyah (definition) by feeding one poor person for each day. If the fear is only for yourself, or for both yourself and the fetus, then you must make up the missed days without offering a fidyah. However, if the fear is only for the fetus, then you must make up the missed days and offer a fidyah, which is feeding one poor person for each day. Scholars have cited the statements of Ibn Abbas and Ibn Umar in their interpretation of the verse: {And upon those who are able to fast, but with difficulty, is a ransom – the feeding of a poor person.}
