Is a wife obligated to fast the entire month of Ramadan that she missed due to pregnancy, or is she required to pay a fidyah, and what is the amount of the fidyah?

A wife must make up for the days she missed in Ramadan due to pregnancy, as Allah Almighty says: "So whoever among you sights the New Moon, he must observe the fast that month, and whoever is ill or on a journey, the same number of other days." If she deliberately delays making up the fast without a valid excuse until the next Ramadan begins, she must make up the fast and pay an expiation (fidyah) for each day. However, if the delay was due to an excuse (such as illness, ignorance, or forgetfulness), she is not required to pay expiation. The amount of expiation is 750 grams of the staple food of the country's inhabitants.
