The presence of a gestational sac in the uterine cavity can be detected at about 6-7 weeks of menopause in women with regular menstrual cycles by ultrasonography. If there is no gestational sac in the uterine cavity, it can be carefully examined to see if there is a gestational sac in the uterine cavity and if a gestational sac or fetal heartbeat is seen outside the uterine cavity, a definite diagnosis of ectopic pregnancy can be made. In addition, it can also be indirectly determined by other auxiliary tests, for example, when the blood HCG test is done at five weeks after menopause, the value is low and the value increases slowly without doubling every other day, and when a pregnancy test is taken, two bars may appear, one deep and one light. It is recommended that women who have a small amount of vaginal bleeding after menopause, especially after menopause, should go to the hospital early for confirmation to see if it is an intrauterine pregnancy. If it is an ectopic pregnancy, treatment should be carried out early to avoid endangering women’s health.
