Generally around six weeks after a missed period, an ectopic pregnancy can be detected through an ultrasound examination. For women with regular menstrual cycles, if menstruation is delayed by a week and a pregnancy test shows a positive result, it indicates pregnancy. At this time, it is necessary to visit the hospital for an ultrasound to ascertain the implantation site of the gestational sac. In the case of an ectopic pregnancy, it is normal that no gestational sac is visible within the uterine cavity during an ultrasound. The ultrasound might reveal irregular echo areas in the adnexal area, which includes the fallopian tubes or ovaries, possibly indicating thickened fallopian tubes or enlarged ovaries. At this point, one should be vigilant about the possibility of an ectopic pregnancy and seek timely treatment.

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.

Does an ectopic pregnancy hurt?

Ectopic pregnancy is an abnormal pregnancy state where the fertilized egg implants outside the uterine cavity. As the pregnancy sac grows, there is a possibility of rupture and bleeding at the implantation site, which can lead to abdominal pain. In the early stages of an ectopic pregnancy, women generally do not exhibit any specific symptoms and are unaware of the condition. Symptoms are only felt when rupture occurs, causing pain in the lower abdomen. If rupture occurs, the pain often feels like tearing in the lower abdomen and is frequently accompanied by nausea and vomiting. It is recommended to promptly visit a hospital for an ultrasound and actively pursue surgical treatment.

Ectopic pregnancy signs

Normally, if menstruation does not occur at the expected time and there is irregular, light bleeding, the first step is to go to the hospital for an early pregnancy test. If the test shows two lines, this indicates pregnancy. Pregnancy includes intrauterine pregnancy and ectopic pregnancy. In cases of ectopic pregnancy, there is generally also irregular bleeding and abdominal pain. Therefore, if the early pregnancy test is positive with two lines and there is irregular bleeding and abdominal pain, one must be alert for the occurrence of an ectopic pregnancy. At this time, you can go to the hospital for blood tests to check the HCG levels and progesterone, along with an ultrasound to comprehensively determine the situation. If there is no gestational sac within the uterine cavity and an abnormal mass is found outside the uterus, then hospitalization and appropriate treatment for the ectopic pregnancy are needed.

What causes an ectopic pregnancy?

Ectopic pregnancy refers to the implantation of a fertilized egg outside the uterine cavity, with tubal pregnancy being the most common type, accounting for up to 95% of cases. There are many causes of ectopic pregnancy, with the main reasons including the following: First, inflammation of the fallopian tubes is a major cause of ectopic pregnancy because the inflammation can cause the mucous membranes of the tubes to adhere, narrowing of the lumen, or impairment of the cilia function, leading to obstruction of the fertilized egg's movement within the tube, preventing it from reaching the uterine cavity, thus, it implants in the tube. Second, the patient has a history of fallopian tube surgery or a previous ectopic pregnancy. Third, poor development or abnormal function of the fallopian tubes. Fourth, the implementation of assisted reproductive technology. Fifth, the intake of emergency contraceptive pills by individuals who experienced contraceptive failure. (The use of medications should be done under the guidance of Doctor Yan.)

Ectopic pregnancy medical conservative treatment

Under normal circumstances, the treatment of ectopic pregnancy is generally divided into conservative treatment and surgical treatment. Conservative treatment is usually applied when the ectopic pregnancy has not ruptured, using medication for about a week. After one week, a follow-up examination is done to check blood HCG levels and an ultrasound scan. If blood HCG levels have dropped significantly, the ultrasound shows that the mass has not grown, and the symptoms of abdominal pain have decreased, it indicates that the conservative treatment was successful. The threat is only considered resolved when blood HCG returns to normal levels. Otherwise, the conservative treatment for ectopic pregnancy may fail, and surgery will be necessary to treat the ectopic pregnancy symptomatically. If there is a particularly large amount of bleeding or a rupture has occurred, surgical treatment is the only option.
