She experienced menstruation while she was young and did not know about the obligation of fasting, so does she have to make up the days she missed?

Question:
May Allah reward you with good, and may He do you good. She says about herself: The monthly excuse came to me, and I was twelve years old. I was young and did not know about the importance of fasting. I would fast and break the fast, until I began to neglect the fasting. I have been in this state for five years. So what is required of me? Do I have to make up the days that passed, knowing that I do not know how many they are? Or do I have to give charity? What do I do in my case? May Allah reward you with good.

Answer:
It is obligatory for you to make up the days of menstruation or the days you broke your fast. The important thing is that it is obligatory for you to make up the days of menstruation that passed during Ramadan, even if they were a long time ago. The obligation to make them up does not drop from you. In addition to making them up, you must feed one poor person for each day. To qualify, you give out half a sa' of food, which is about one and a half kilograms, for each day, to be paid to the poor. You give it to one poor person. But for each expiation. The one poor man. Yes, or... and praise be to Allah.
As for the length of the time, it does not invalidate the obligation to make up the fasts because they remain in your liability. As for the fact that you do not know the number, you should refer to your monthly custom, the number of days you know. If it is difficult for you, you must estimate, investigate, and be cautious.
