If the low menstrual flow is caused by damage to the lining of the uterus, conception is not easy in this case. For example, if the patient has a history of multiple uterine operations, a thin endometrium, or adhesions in the uterine cavity or cervical canal, it is very difficult to conceive in this case. In addition, if the patient has a Mycobacterium tuberculosis infection, Mycobacterium tuberculosis destroys the uterine lining and causes damage to the uterine lining, in which case the woman is also not susceptible to conception. If the low menstrual flow is simply decreased and is not combined with other problems, pregnancy will not be affected in this case. If the menstrual flow is anovulatory, it is not easy to conceive, and ovulation stimulation treatment should be given if necessary according to the condition.
