What should one who is unable to seek out Laylat al-Qadr due to a Shar'i (Islamically lawful) excuse do, and will she miss out on the reward, and is it permissible for her to use pills to delay menstruation if the answer is yes?

A menstruating woman can seek Laylat al-Qadr through remembrance (dhikr), reciting the Qur'an, supplication (du'a), seeking forgiveness (istighfar), and giving charity (sadaqah). She can perform every good deed that does not depend on ritual purity from menstruation. It is also permissible for her to use menstruation-delaying pills to witness Laylat al-Qadr while ritually pure.
