When the pregnancy stops at 9 weeks, there may be symptoms such as disappearance of early pregnancy symptoms, vaginal bleeding, abdominal pain and so on. 1. Disappearance of early pregnancy reaction: Generally, women will have early pregnancy reaction, such as nausea, vomiting, drowsiness, fatigue, breast swelling and pain, etc., which will be stimulated by hormones before 12 weeks of pregnancy, and the early pregnancy reaction will be suddenly alleviated or disappeared when the fetus stops. 2. Vaginal bleeding and abdominal pain: when the embryo stops developing, the placental tissue loses its blood supply and will gradually detach from the uterus, which will stimulate uterine contraction in the process, resulting in the symptoms of vaginal bleeding and abdominal pain. In addition, after 9 weeks of pregnancy, the value of HCG will be decreased in the blood test, and the disappearance of fetal heart can be seen in ultrasound examination. However, some women may not show any obvious symptoms after the abortion, so they need to go to the hospital for relevant examinations to make a clear diagnosis. After confirmation of fetal arrest, treatment should be carried out under the guidance of the doctor in time to expel the embryonic tissue and avoid inflammatory reactions.
