Some women use certain pills to delay the onset of their monthly period so as to be able to perform their religious obligations, such as fasting and hajj rituals. These pills upset the equilibrium of hormones in the body, which in turn affect the period, rendering it irregular, so much so that the duration, when the woman is tahir, is some ten days or more or slightly less. It is worth noting that the type of blood, of menstruation during this time, is identical to that which the woman witnesses during her regular period. What is the ruling on this matter?
Answer
If the number of days of her being Tahir is ten days or more, the blood that appears before this duration and that which follows it should be treated as two separate Haydh (menstruation). Should the duration of being Tahir be less than ten days, and the total of the two bloods and the intervening Tahir duration are more than ten days, the blood that coincides with the days of the period, not the other one, is considered Haydh, the other Istihadha (undue menses), as a matter of course, except when that which is in the period is ahead, and the second blood bears the characteristics of Haydh. In this case the part which is not exceeding ten days is allotted to the first haydh, even if it does not coincide with the days of period and the woman not being of an irregular period. If any one of them fulfils the conditions of period, she must consider the one that does as Haydh and the other, that does not, Istihadha. If both are equal, the inclination is to make the first Haydh, irrespective whether or not the two demonstrate the signs of Haydh.
