As long as there is no abdominal pain or bleeding, it does not necessarily mean that ectopic pregnancy is not ectopic. Some ectopic pregnancies do not have abdominal pain or vaginal bleeding for a certain period of time, and at this time it is most important to perform the appropriate HCG test and ultrasonography if there is a clear history of menopause. If the HCG indicates a pregnancy, and the ultrasound suggests the presence of abnormal echoes in the adnexal region, or even if the ultrasound suggests the presence of a gestational sac or fetal buds, ectopic pregnancy needs to be highly considered, and even if there is no abdominal pain or vaginal bleeding, the pregnancy should be followed up aggressively. If the ultrasound already suggests the presence of clear fetal buds, it is necessary to perform appropriate surgical treatment as soon as possible in order to be safer, if not treated in this way is likely to break through the intra-abdominal hemorrhage, triggering hemorrhagic shock.
