Ectopic pregnancy, as the name implies, is a pregnancy in which the embryo lays outside the body of the uterus, and the most common type of ectopic pregnancy is tubal pregnancy. Both ectopic pregnancy and normal pregnancy will show menopause and positive urine HCG or even early pregnancy reaction, but because the fallopian tube cannot provide the growth space and nutritional support that the normal uterine cavity can provide, tubal pregnancies often miscarry or rupture, resulting in several typical symptoms of ectopic pregnancy. 1. Menopause: Most ectopic pregnancies have a history of menopause of about 6-8 weeks, but about 25% of patients have no obvious history of menopause or treat irregular bleeding after ectopic pregnancy as menstruation, but irregular bleeding is usually different from the bleeding time and nature of normal menstruation. 2. Abdominal pain: About 95% of patients present with abdominal pain. Before the rupture of tubal pregnancy or miscarriage, the embryo gradually grows in the fallopian tube, which usually manifests as hidden pain or distension in the lower abdomen of the affected side. When the blood stimulates the diaphragm, there may be chest pain and shoulder pain. Vaginal bleeding: Since the embryo of ectopic pregnancy is prone to miscarriage, HCG may not rise well or even fall, and the hormone secreted by the corpus luteum is not enough to support the growth of the meconium, so irregular vaginal bleeding may occur, but the bleeding volume is usually less than the normal menstrual volume, dark red or brown, and in a few patients, the vaginal bleeding may resemble the menstrual volume and may be accompanied by meconium discharge. 4. Syncope and shock: In case of tubal pregnancy rupture or miscarriage, intra-abdominal bleeding and severe abdominal pain may cause syncope and hemorrhagic shock, and the degree of shock does not correspond to the degree of external bleeding. The common symptoms of hemorrhagic shock are pale skin, increased heart rate, decreased blood pressure, wet and cold extremities, dizziness, and irritability. 5, other: abdominal mass: If the bleeding in the abdominal cavity is slow, a hematoma can be formed, and the surrounding tissue adhesions wrapped to form a mass, and the larger masses can be found in the abdomen. Hypothermia: Patients usually have normal body temperature, and may have hypothermia when the blood accumulates in the abdominal cavity is absorbed. Gastrointestinal symptoms: Intra-abdominal bleeding can irritate the intestine and cause nausea and vomiting, and patients with high HCG may also have mild early pregnancy reaction. In the early stage of ectopic pregnancy, when tubal pregnancy miscarriage or rupture has not occurred, the symptoms are not obvious and are similar to normal pregnancy or pre-eclampsia. Therefore, it is recommended that women who are preparing for pregnancy with a positive self-test for urine HCG should visit the hospital as soon as possible to monitor blood HCG and ultrasound. Patients with irregular vaginal bleeding and lower abdominal pain, especially if they have a history of ectopic pregnancy, also need to be seen for examination as soon as possible.
