How to differentiate spontaneous abortion

For every pregnant mother, having a baby is probably the most important thing in their hearts. They hope that after ten months of pregnancy, they can give birth to a healthy baby, which is their greatest happiness. However, things go against their wishes. Spontaneous miscarriage often happens around us. A healthy newborn baby often disappears. So, how to differentiate and diagnose spontaneous miscarriage?

(1) Amenorrhea time: Except for the longer amenorrhea time of tubal interstitial pregnancy, most patients have a history of amenorrhea of ​​6 to 8 weeks. 20% to 30% of patients have no obvious history of amenorrhea and may mistake irregular vaginal bleeding for the last menstruation, or may not consider it as amenorrhea because the menstruation is only a few days overdue. However, the amenorrhea time of miscarriage can be longer.

(2) Amount and color of vaginal bleeding: Tubal pregnancy often causes vaginal spotting, which is dark brown in color and small in amount, usually not exceeding the amount of menstruation. It is continuous and may be accompanied by the discharge of decidual casts or decidual fragments. Vaginal bleeding usually stops after the lesion is removed. In case of miscarriage, the amount of vaginal bleeding usually increases gradually, starting with bright red, and turning into dark red or brown if the bleeding lasts for a long time.

(3) Abdominal pain: Before tubal pregnancy abortion or rupture, it is often manifested as dull pain or soreness on one side of the lower abdomen. When abortion or rupture occurs, the patient suddenly experiences tearing pain on one side of the lower abdomen, often accompanied by nausea and vomiting. In severe cases, syncope and shock may occur, accompanied by frequent urge to defecate and discomfort in the anus. The abdominal pain of abortion is paroxysmal, especially in the middle of the lower abdomen, and varies in severity from mild pain to obvious spasmodic pain.

(4) Gynecological examination: In tubal pregnancy, the posterior vaginal fornix is ​​full and tender, and the cervix is ​​obviously tender when raised. This is one of the main characteristics of tubal pregnancy. The uterus is slightly enlarged and soft. When there is a lot of internal bleeding, the uterus feels floating during examination. A mass with unclear boundaries can be felt on one side of the uterus or behind it, and it is obviously tender.

(5) Auxiliary examinations: ① Dark red non-coagulated blood is drawn out during puncture of the posterior vaginal fornix, which can assist in the diagnosis of tubal pregnancy; ② A positive urine pregnancy test, but the patient's HCG level is significantly lower than that of intrauterine pregnancy; ③
