As we all know, the normal site of fertilization for women is the fallopian tube, and through travel, the fertilized egg eventually settles in the uterine cavity, but if for some reason the fertilized egg “settles” in the wrong place and “lands” and grows outside the uterine cavity, it is an ectopic pregnancy, which is often referred to as “ectopic pregnancy. If for some reason the fertilized egg “settles” outside the uterine cavity and grows, this is called ectopic pregnancy, or “ectopic pregnancy” as it is often called. Ectopic pregnancy is a hidden killer Ectopic pregnancy occurs mostly in the fallopian tubes, especially in the jugular area of the fallopian tubes. In addition, pregnancy in the horn of the uterus and cervical area, ovarian pregnancy and abdominal pregnancy are all ectopic pregnancies, among which tubal pregnancy is the most common, accounting for about 95 percent. Ectopic pregnancy is an invisible killer that occurs insidiously. There are two reasons for its invisibility. 1. Some women are pregnant but do not know it; 2. Some women find that they are “pregnant” and have no discomfort, so they often do not have their first ultrasound until they are 2 to 3 months pregnant, so they fail to detect ectopic pregnancy early. In fact, after 40 days of menopause, vaginal ultrasound examination and blood HCG measurement can basically assist doctors in early diagnosis of ectopic pregnancy, but pregnant women often neglect the early diagnosis of ectopic pregnancy. When an ectopic pregnancy reaches 40 to 50 days, if it is not detected or treatment measures are not taken in time, tubal rupture may occur, resulting in massive abdominal bleeding and even life-threatening. Therefore, ectopic pregnancy is also one of the leading causes of death in women in early pregnancy. What are the warning signs of ectopic pregnancy Ectopic pregnancy actually has warning signs. You must pay attention when the following three alarms are sounded 1. Brief history of menopause or delayed menstruation with irregular vaginal bleeding. Most patients with ectopic pregnancy have a history of menopause of varying lengths, usually 6 to 8 weeks, while 30% of patients have no obvious history of menopause but have irregular vaginal bleeding, which is small, dripping and dark red. Some patients with irregular vaginal bleeding may be diagnosed as having a “pre-eclampsia” and be put on birth control. At the same time, there are no typical symptoms in the early stage of ectopic pregnancy, which makes the condition delayed and makes treatment more difficult. 2. Abdominal pain. This is another most common symptom of ectopic pregnancy, which can be hidden pain, swelling, cramping, colic or tearing pain. Such abdominal pain, which occurs continuously or intermittently, can also be sudden. 3. pelvic mass. The hematoma formed by the miscarriage or rupture of tubal pregnancy adheres and wraps around the surrounding tissues and organs to form a mass.
