How to describe it in one sentence?

In a word, describe menstrual discomfort:

1. If I die this afternoon, I must have died of dysmenorrhea. It happens that I have my period on Thursday, I have dysmenorrhea on Thursday afternoon, and I have to check my hygiene on Thursday afternoon, but there can't be anyone in the dormitory when checking my hygiene. Everything is so unfortunate.

2. It is better to wake up after a painful sleep. I went for an injection in high school, and then I solved it directly with painkillers.

Before my period, I was crazy about eating anything. Now everything hurts after I first came here. How can this be ordinary? I'm already dead.

4. The brain stops working completely, the eyes are shining, or sometimes it is black, and the whole face is not half bloody.

Before going to bed every night, I feel so angry that I want to swear. I didn't have my period the next day and continued to be constipated. I was really crazy at that time, torturing myself with other people's costumes.
