A woman may not necessarily get pregnant if she has low menstrual flow, which needs to be analysed in the context of the cause of the problem, as follows: 1. If there is no ovulation and the endometrium is not thin, it will not affect conception, and a woman can get pregnant normally; 2. If the low menstrual flow is due to anovulatory menstrual disorders, it will affect conception, and if ovulation does not occur, then sperms and eggs will not be able to meet to form a fertilised egg, and a woman will not get pregnant; 3. If low menstrual flow is due to damage to the endometrium, it will affect pregnancy, such as a history of repeated uterine operations, which can cause thinning of the endometrium, or a previous case of Mycobacterium tuberculosis, which can cause damage to the endometrium.
