What is the ruling on a girl fasting and praying if her menstrual period began before Ramadan and continued for about a month, with the discharge of blood clots, and how should she make up for the missed days from the previous Ramadan?

A woman whose menstrual period continues for more than fifteen days is considered to be experiencing istihadha (non-menstrual vaginal bleeding). She must take precautions, perform ablution, pray, and fast after the time for each prayer begins. Bleeding considered istihadha does not permit abandoning fasting unless it affects her health. If a woman abandons prayer and fasting due to ignorance, she must repent and make up the missed prayers, with the exception of the days of menstruation, and make up the days she missed from Ramadan (definition), because she should have asked those knowledgeable in religious matters. She is not required to pay an expiation for delaying the making up of fasts if the delay was due to illness or menstruation. However, she must make up the missed days after Ramadan and after she is able to do so.
