If there is no obvious menstrual pain when menstruating, it will have no effect on the examination. Most people will have a slight lower abdominal cramping when menstruating, which is normal, and the pain will generally disappear after about 1 day. If you can tolerate the pain, you don’t need special treatment, and you don’t need to change your menstrual cycle, so it won’t have a big impact on your exams. If the dysmenorrhea is very serious, then it may affect the examination. In this case, the medication can be used in advance, and short-acting oral contraceptives can be applied 2 months before the examination to advance or postpone the menstrual cycle.
