Auntie refers to menstruation. If you test pregnant but have menstruation, it may not be menstruation but abnormal vaginal bleeding, which may be related to miscarriage with aura, ectopic pregnancy, etc.; or you may have a false-positive result when you test pregnant. 1. Pre-eclampsia: In early pregnancy, when the embryo, the mother and the environment cause the embryo to stop, triggering pre-eclampsia, there may be vaginal bleeding, abdominal pain and other symptoms, which the pregnant woman may mistake for menstruation. 2. Ectopic pregnancy: the fertilized egg is deposited in a part of the uterine cavity other than the uterine cavity, and may rupture when it develops to a certain stage, which may also cause vaginal bleeding, severe abdominal pain and other discomforts. 3. Examination error: If pregnancy is detected by using pregnancy test paper, there may be false positive results. This means that you may not be pregnant, but just have a delayed period, and then have your period again some time later. If you are pregnant but have vaginal bleeding, it is recommended that you go to the hospital for ultrasound of the uterine adnexa, human chorionic gonadotropin and other tests to determine the cause of the disease and treat the cause under the guidance of the doctor.
