Women who have elevated levels of human chorionic gonadotropin in their blood after menopause, which is a cystic structure on ultrasound, can usually turn into a smaller gestational sac around 35 days after menopause for women with normal, regular menstrual cycles. If a woman has delayed menstruation or if the fertilized egg is slower to implant and develop in the uterine cavity, she may not have a gestational sac until 40-50 days after menopause. If imaging suggests a cystic dark area in the uterine cavity, there is no yolk sac in the uterine cavity and the report presents as a cystic structure. If the woman does not have lower abdominal pain or vaginal bleeding at this time, she can be temporarily observed and it is recommended to check again after 35 days of menopause, when a gestational sac can appear in the uterine cavity along with a punctate fetal bud, which proves a normal intrauterine pregnancy and basically excludes ectopic pregnancy. If the gestational sac is still not seen after about 50 days of menopause and the level of human chorionic gonadotropin is not significantly elevated, the presence of ectopic pregnancy is suspected and the diagnosis needs to be actively confirmed. After pregnancy, women should pay attention to rest, avoid staying up late, keep the vulva clean, and not have sex in early pregnancy. She should eat a light diet and pay attention to balanced nutrition. If there is lower abdominal pain and a small amount of vaginal bleeding, you need to go to the hospital in time to check if there is a preterm abortion.
