How to determine whether the gestational sac is discharged or not can be done in two ways: 1. you can see visually whether the gestational sac is discharged or not, a normal gestational sac is discharged with intact chorionic membrane and can be flushed at the water pipe, the chorionic hairs are white as well as hairy; 2. you can observe whether there is still a gestational sac in the uterine cavity by going to a regular hospital for ultrasound examination. If there is residual or there is a gestational sac, it is recommended to take the next step of treatment, such as cleaning the uterus or using medicine again. The main thing to look at is the bleeding situation. If there is too much bleeding, it is still necessary to treat the uterus with timely evacuation. It is necessary to use some anti-inflammatory medication to prevent infection and to review the ultrasound regularly to see how the uterus is recovering.
