Women with a history of normal menstruation who have a history of sexual intercourse and present with non-menstrual bleeding need to be alerted to the possibility of an abnormal pregnancy. This situation requires prompt consultation for ultrasound and human chorionic gonadotropin levels. If the blood tests are higher than normal, it means that you are pregnant. Depending on the development of the gestational sac, it can be found either intrauterine or extrauterine, so that the diagnosis of intrauterine pregnancy, pre-eclampsia or ectopic pregnancy can be made. Sometimes the diagnosis is difficult and needs to be combined with a posterior vault aspiration or other complementary tests. Sometimes, women may experience a small amount of bleeding after their menstruation because of mental stress, change in work and rest, etc. As long as the test results are normal, there is nothing to worry about and no special treatment is needed in this case. Adjust your mind, regular work and rest, you may be able to resume normal menstruation in the following month.
