Whether dysmenorrhea affects pregnancy cannot be generalized. Dysmenorrhea can be divided into primary dysmenorrhea, which is physiological, and secondary dysmenorrhea. Primary dysmenorrhea refers to cases where there are no pathological changes in the female reproductive organs, and the pain is solely due to uterine contractions during menstruation, commonly seen in adolescent girls. Moreover, conditions such as adenomyosis, severe uterine fibroids, and endometriosis can also cause pain and are associated with changes in the uterus, which can affect pregnancy. However, primary, functional dysmenorrhea generally does not impact the ability to conceive. Thus, whether dysmenorrhea affects pregnancy depends on the specific circumstances.
