What should I do if I have a stomach ache at school, the problem is that the class time is not long,

I feel the same way, sometimes I really have a stomachache, and there are many people in the toilet, and it's really annoying, but I always ask the teacher for leave in class, and I scold when I am scolded, which is better than a bunch of people walking around after class, and I just wait, and wait for noon when there are fewer people.

I go to the toilet at school as long as the tuba first finds someone less, if there is no more people, it doesn't matter, go to the toilet with peace of mind, it doesn't matter if the class bell rings, I know that nothing is more important than my own business.

Be physical! If you don't feel well during class, take time off to go to the bathroom, and go to the toilet when you don't feel well after class.

In short, the body is the capital of the revolution, and everything must be based on the body. I believe the teacher will understand (don't worry about being late, you can preview and generally a few minutes before class, the teacher is solving the problem, not talking about the key points, just return to the classroom within five minutes of class, it's OK).

Take a leave of absence and go to class, just less embarrassed
