Can I Take A Pill To Supress My Menstruation?

1) At the outset, a woman should keep record of her menstruation habit. If she intends on performing Umrah, she should plan her dates in a way that she can perform her Umrah when she is in the state of purity.

If it is not possible for her to perform her Umrah during her normal days of purity, and she is in her menses, she may use medication to supress her menstruation. She may then perform Umrah in that state as well as other regular acts of worship.[i] However, she should not  have conjugal relations until the regular days of her menses are complete.[ii]  For example, if a woman has a regular menstruation habit of six days, she should not have conjugal relations until six days are complete.

Furthermore, in the case that she observes blood or discharge within fifteen days of the blood stopping, this will render the days of her regular habit as days of haidh. For example, if a woman’s menstruation habitually occurs during the first six days of the month, and she took a pill to supress the menstruation on the first day. However, within fifteen days, she started spotting blood. In that case, the six days of her habit would be in the ruling of haidh.

Hence, she would have performed umrah in the state of impurity. As such, she would be obligated to pay dam (ritual sacrifice). Alternatively, she may avoid the dam by performing tawaf in the state of purity. [iii]

The above has been given due to necessity and is contrary to the normal ruling. In general, if a woman takes medication to supress her menstruation, she will be regarded to be in the state of menstruation until the completion of her normal habit. [iv]

As for the second part of your question, if she remains clean for fifteen days, the first day will be regarded as istihaadah. However, if she observes blood or discharge within fifteen days, this day along with the days of her habit will be in the ruling of haidh.

2) In principle, it is forbidden for a woman to enter the masjid during her menses. [v]Accordingly, it will be forbidden for a female teacher to teach in the masjid during her menses. However, a distinction must be made between the Shar’ee Masjid and the building. The place that is forbidden for a woman to enter is the actual Shar’ee Masjid. A woman can enter the building as long as she does not enter the actual Shar’ee masjid. Therefore, if the classes are being conducted in such a place that is not part of the actual Masjid, for example, a classroom in the building, etc, then it will be permissible.
