Task: Question Answering
Input (English): Context: Just four days until we leave for Norway ! Because the Viking Queen is getting married next week , I had to spend a large chunk of my weekend in malls looking for something classy to wear . I enjoy shopping for clothes about as much as I enjoy menstrual cramps . Lucky for me , I got to experience both of these things at the same time over the weekend . 
Question: What may be the reason for their discomfort ?
Output (English): They had started their period before the wedding .
