Therefore, it is a simple, efficient and safe contraceptive method. Of course, it is not foolproof. There is a certain probability of pregnancy while wearing an IUD. Of course, this probability is very low. Let's take a look at this aspect.

The chance of ectopic pregnancy with an IUD

In general, the possibility of accidental pregnancy due to ring displacement is considered. At the same time, considering the pregnancy after IUD insertion, the possibility of ectopic pregnancy is still relatively high, so if the test is positive, it is best to choose B-ultrasound examination about 6 weeks after menopause to determine whether there is a gestational sac.

Ectopic pregnancy refers to any pregnancy that occurs outside the uterus, while ectopic pregnancy refers to a pregnancy in which the fertilized egg is located outside the normal implantation site. It also includes cervical pregnancy, intramural pregnancy, cornual pregnancy, etc. Therefore, ectopic pregnancy has a broader meaning and is accepted by the obstetrics and gynecology community. Ectopic pregnancy is a common gynecological acute abdomen, and its incidence has been on the rise in recent years.

Early symptoms of ectopic pregnancy

(1) Amenorrhea: Except for interstitial pregnancy with a long history of amenorrhea, most cases have amenorrhea for 6 to 8 weeks. About 20 to 30% of patients have no obvious history of amenorrhea.

(2) Abdominal pain: It is the main reason for patients with tubal pregnancy to seek medical treatment. Before tubal pregnancy miscarriage or rupture, symptoms include dull pain or soreness in one side of the lower abdomen. When miscarriage or rupture occurs, the patient suddenly feels tearing pain in one side of the lower abdomen, often accompanied by nausea and vomiting. If blood accumulates in the rectouterine pouch, there is a feeling of heaviness and distension in the anus. Internal bleeding increases, and blood flows from the pelvic cavity to the entire abdomen, causing general abdominal pain. Stimulation of the diaphragm can cause radiating pain in the shoulder blades.

(3) Vaginal bleeding: There is often irregular vaginal bleeding, which is dark red in color, small in amount, and continuous, usually not exceeding the amount of menstruation. Decidual casts or fragments may be discharged with the vaginal bleeding.

(4) Syncope and shock: Due to acute intra-abdominal bleeding and severe abdominal pain, the patient may suffer from syncope in mild cases and hemorrhagic shock in severe cases. Its severity is proportional to the rate and amount of intra-abdominal bleeding, but not proportional to the amount of vaginal bleeding.
