Is it permissible to fast and pray in two cases: first, when intestinal bleeding occurs due to medication outside of the menstrual period, and second, when intermittent bleeding or clots appear after menopause, with doctors confirming that there is no health issue?

The default assumption for blood discharged by a woman is that it is menstrual blood, unless there is another cause, such as intestinal bleeding. Menstrual blood is dark and recognizable. If it is bleeding, prayer and fasting are obligatory. Despair has no specific age. So, if a woman sees the familiar menstrual blood, it is menses even if she is seventy years old. The decisive factor is the cessation of blood, not age. As for non-continuous spots and drops, they are not menses, and it is advisable to consult doctors.
