In the case of ectopic pregnancy, there is a 60-80% chance that there will be bleeding, or no bleeding. In early ectopic pregnancy, there are no abnormal changes when it is first detected and there is no bleeding. As the adnexal mass continues to increase in size, there will be pelvic bleeding, including vaginal bleeding, which may be similar to or less than menstrual flow, with no fixed duration. The first step to determine if the pregnancy is ectopic is to combine HCG and abdominal ultrasound. In the early stage, if there is no way to confirm the diagnosis, it should be observed for 5-7 days more. When a tubal mass is present, if the mass is small, conservative treatment can be performed to help kill the embryo and restore the normal tubal shape. If the mass is relatively large, laparoscopic bilateral tubal window retrieval can be chosen, otherwise there is a chance of hemorrhage for a long time.
