What should I do if hcg drops during ectopic pregnancy?

Some women are found to be pregnant, but the fertilized egg does not implant in the uterus, but outside the uterine cavity. People call this condition ectopic pregnancy, which is a very abnormal pregnancy process. Ectopic pregnancy, like normal pregnancy, will cause women to have some pregnancy reactions, such as cessation of menstruation. When the ectopic pregnancy reaches a certain period, abdominal pain will occur. In addition, hcg will also drop significantly. How to solve this problem?

What should I do if hcg drops during ectopic pregnancy?

How can I know for sure whether I am pregnant, whether it is a real pregnancy or a false pregnancy, an ectopic pregnancy, or intrauterine fetal maldevelopment? It is impossible to make a diagnosis by B-ultrasound in the early stages of pregnancy, but now it can be determined by blood HCG. Blood HCG is not only highly sensitive, but also can be used for accurate judgment because it is "quantitative" data.

HCG (human chorionic gonadotropin) is the "pregnancy test" hormone that is familiar and most commonly used by obstetricians and gynecologists. It is composed of glycoproteins of α and β dimers. But the α-subunit is common to all anterior pituitary hormones. The β-subunit is specific to HCG.

The complete HCG is produced entirely by the syncytiotrophoblast of the placental chorion. Its main function is to stimulate the corpus luteum, which is beneficial to the continuous secretion of estrogen and progesterone, so as to promote the formation of uterine decidua and make the placenta grow and mature. It is now believed that HCG is produced by trophoblast transitional cells and syncytial cells. It increases rapidly during the first 8 weeks of pregnancy to maintain the pregnancy. After about 8 weeks of pregnancy, HCG gradually decreases until it reaches a relative stability around 20 weeks.

Normal reference value: The normal value of blood HCG is <10μg/L, and the normal value of β-HCG is <3.1μg/L.

The absolute values ​​of serum HCG vary greatly during different periods of pregnancy and between pregnant women. They are different from person to person and are not comparable. They can only be compared within themselves. For normal non-pregnant women: blood HCG <100IU/L. During the first 3 months of pregnancy, the HCG level approximately doubles every 2.2±0.5 days.

Urine-HCG (HCG semi-quantitative method): non-pregnant women <25IU/L, 40 days of pregnancy >5000IU/L, 60-70 days of pregnancy >(8-32)×104IU/L (urine HCG level is highest in the early morning, close to serum level)

Ectopic pregnancy will cause pregnancy reactions. An abnormal pregnancy process in which the fertilized egg implants and develops outside the uterine cavity. Commonly known as ectopic pregnancy. The most common type of pregnancy is tubal pregnancy. There are often no obvious symptoms before miscarriage or rupture, but there may also be amenorrhea, abdominal pain, and a small amount of vaginal bleeding. After rupture, symptoms include acute and severe abdominal pain, repeated attacks, vaginal bleeding, and even shock. Examination often shows signs of intra-abdominal bleeding and a mass next to the uterus. Ultrasound examination can assist in diagnosis. After an ectopic pregnancy, some pregnancy reactions may occur due to the increase of progesterone in the body.
