Must a mother make up the days on which she saw spotting, or intermittent black discharge, during her fasting of two consecutive months for expiation, and must she repeat the month of fasting because she broke her fast on a day, thinking that her menstrual period had begun?

Dark discharge during menstruation is considered part of the menstrual period. Therefore, a woman must make up the days she experienced this dark discharge, regardless of whether she broke her fast or not, because her fast is invalid due to the presence of menstruation. The continuity of two consecutive months of fasting is not interrupted by menstruation.
