The precursors of an ectopic pregnancy can manifest as unilateral lower abdominal dropping pain, and there may be irregular vaginal bleeding. After 50 days of pregnancy, the gestational sac is not visible in the uterine cavity, and the symptoms of an ectopic pregnancy are atypical. Some people may experience severe bleeding and go into shock. In cases of ectopic pregnancy, it is imperative to go to the hospital for an ultrasound to determine the size and location of the gestational sac and confirm whether it is an ectopic pregnancy. Timely hospitalization and treatment are necessary if an ectopic pregnancy is confirmed.

Early symptoms of ectopic pregnancy

Ectopic pregnancy, also known as extrauterine pregnancy, refers to the implantation of the gestational sac outside the uterine cavity. For example, in the fallopian tubes, ovaries, or the cornual region, etc., leading to a series of symptoms known as ectopic pregnancy. Typically, symptoms of an ectopic pregnancy include a history of amenorrhea, where most individuals have a long or short history of missed periods. The second symptom is bleeding, which can be irregular, minor vaginal bleeding or significant bleeding, as well as bleeding within the abdominal cavity, which can lead to hemorrhagic shock in severe cases. Additionally, abdominal pain may occur, manifesting as sudden, tearing-like lower abdominal pain, or irregular referred pain.

Is the probability of ectopic pregnancy high?

Ectopic pregnancy, as the name implies, refers to the implantation of the fertilized egg outside the uterine cavity, not within the uterus. Ectopic pregnancies most commonly occur in the fallopian tubes, accounting for about 95% of cases. Ectopic pregnancy is one of the common emergencies in gynecology and obstetrics, but its incidence is actually not high, approximately 2%-3%. However, because ectopic pregnancy is a leading cause of death in early pregnancies, it is quite alarming. In recent years, however, with the advancement of ultrasound technology, ectopic pregnancies are being diagnosed and treated earlier, significantly enhancing the survival rates and the ability to preserve fertility.

How is an ectopic pregnancy caused?

Ectopic pregnancy refers to the implantation of a fertilized egg outside the uterine cavity. A pregnancy located outside the uterine cavity is commonly known as an ectopic pregnancy. The most common type of ectopic pregnancy is a tubal pregnancy, though less common types include abdominal, ovarian, and cervical pregnancies. How does an ectopic pregnancy occur? Inflammation is the most common cause, as it can lead to adhesions in the fallopian tubes or pelvic area, causing abnormal transport in the fallopian tubes. Additionally, ectopic pregnancies can result from scarring after surgeries, such as pregnancies in cesarean section scars, and from anomalies of the uterus, like pregnancies in a remaining part of the uterus.

ectopic pregnancy symptoms

Ectopic pregnancy is not a normal state of pregnancy. Normally, the gestational sac should be located in the middle of the uterine cavity. An ectopic pregnancy refers to the implantation of the gestational sac outside the uterine cavity. Common types of ectopic pregnancy include tubal pregnancy, ovarian pregnancy, and abdominal pregnancy, with over 99% of ectopic pregnancies being tubal pregnancies. The symptoms of an ectopic pregnancy include the following aspects: 1. In the early stages of an ectopic pregnancy, there are no clinical symptoms because the early gestational sac is relatively small and does not stimulate the fallopian tube or the local area, thus causing no symptoms. 2. When the gestational sac grows to a certain size, it compresses the tube cavity, causing mild abdominal pain. This pain intensifies as the gestational sac grows and can lead to tearing pain, indicating a ruptured tubal pregnancy. 3. During an ectopic pregnancy, because the gestational sac cannot develop normally, the levels of estrogen and progesterone in the body are relatively low, leading to endometrial withdrawal bleeding, which manifests as a small amount of bright red vaginal bleeding.

What should I do about an ectopic pregnancy?

Ectopic pregnancy, as the name suggests, refers to the implantation of the gestational sac outside the uterine cavity, with the more common types including tubal pregnancy, ovarian pregnancy, and abdominal pregnancy. Ectopic pregnancy is mainly diagnosed through ultrasound and blood tests. If an ectopic pregnancy is confirmed or highly suspected, treatment should begin, primarily choosing between conservative medication treatment or surgical treatment based on the severity of the condition. 1. If the condition is mild, with HCG levels less than 1000 U/L and the mass volume smaller than 3 cm, conservative medication treatment can be chosen. 2. If the condition is severe, with a larger mass volume and significantly elevated HCG levels, surgical treatment is recommended. Currently, with the advancement of minimally invasive surgery, the majority of ectopic pregnancies can be treated using laparoscopy.
