Do yellowish discharges invalidate the fast after the cessation of menstrual bleeding? What is the ruling on fasting two days during which there were transparent discharges with a faint red dot, and are they considered menstruation or istihadah (non-menstrual bleeding)? Is it obligatory to make up the days about whose purity there was doubt? What is the number of days that must be made up if the days of one's usual period cannot be determined? Is it valid to rely on the white discharge (al-qassah al-baida') as a sign of purity if it appears intermittently or with dryness? Can the signs of purity occur together? What is your advice regarding making up the Ramadan fast and then fasting the six days of Shawwal, with the fear of menstruation overlapping? Is the fast of a day to be made up if blood is seen after the Maghrib adhan and it is not known when it descended?

Yellowish discharge after seeing dryness as a sign of purity is not considered menstruation unless it is connected to blood or occurs during the usual period. Fasting on these two days is valid, and there is no need to make up for them. This yellowish discharge is impure, and one must perform istinja' (washing) after it. Purity is indicated either by dryness or by the white discharge (al-qassah al-bayda'). Whichever sign appears first indicates purity. If there is doubt about the time of blood discharge, it should be attributed to the nearest probable time. Blood discharged during a period when menstruation is possible is considered menstruation. There is no need to actively check for any discharge; acting upon the original state of purity is sufficient. One can fast to make up for missed days (qada') and perform voluntary fasts immediately upon seeing the sign of purity. Fasting before seeing red discharge is valid. It is advised to dismiss doubts and turn away from obsessive thoughts.
