The reason for women to have two periods in a month after a small abortion may be the following: First, it is because of problems with the endocrine system. Because the formation and excretion process of female menstruation is very closely related to the endocrine system, if the endocrine system is dysfunctional, it can lead to abnormal content of estrogen, sex hormone, progesterone, follicle stimulating hormone and luteinizing hormone in the body, thus leading to the inability to regulate normal menstruation, which can lead to twice a month menstruation after female mini-abortion; secondly, it may be because the organism has infection, because when When women suffer from acute gynecological inflammation, such as acute vaginitis, acute pelvic inflammatory disease, endometritis, ovarian inflammation, tubal inflammation, cervicitis, etc., these gynecological inflammatory diseases, inflammation can lead to endocrine dysfunction, which can also destroy the formation and excretion process of menstruation, which can also lead to the abnormal situation of women having two periods a month after a small abortion.
