Must a woman who broke her fast for a number of days in Ramadan due to pregnancy-related bleeding, and does not remember the exact number of these days after about six years, make them up?

If you broke your fast due to bleeding (fearing for yourself or the fetus), you must make up the days you missed.

If breaking the fast was due to fear for the fetus only, you must make up the fasts in addition to offering expiation by feeding one needy person for each day.

Feeding is also required for each day that making up the fast was delayed until after the following Ramadan, unless the excuse persisted, in which case no expiation is required.

If you do not know the exact number of days, then fast for the number of days you most likely believe it to be.

The feeding expiation is not repeated for delaying making up the fast for two Ramadans or more without an excuse; you are only required to pay one fidya (ransom) along with making up the fast.
