Do I have to make up the days I missed in the last Ramadan due to pregnancy and fear for the fetus, knowing that I paid the Fidyah and did not make them up, and how do I make them up after another Ramadan has passed?

The pregnant and breastfeeding woman, if they break their fast, are obligated to make up the missed days (qada'), and the fidyah (expiatory feeding) alone is not sufficient according to the majority of scholars. The fidyah (feeding a poor person for each day) is also obligatory along with the qada' if breaking the fast was solely for the sake of the fetus. The missed days must be made up even if the next Ramadan begins, because qada' is a debt. If she delays making up the days without a valid excuse and was aware of the prohibition of delaying, then she must pay a fidyah of feeding a poor person for each day. However, if she was ignorant of the prohibition of delaying, then there is nothing upon her.
