Medicine flow discharges a big blood clot, not sure whether it is a pregnancy sac, how to do

Under normal circumstances, about six hours after the abortion, the pregnancy sac in the body will be discharged. The texture is similar to white tissue. The blood clot you expel may not be a pregnancy sac. It is recommended that you go to the hospital for a review in time after the abortion to determine whether the pregnancy sac in the body has been completely discharged. If it is not completely discharged, you need to undergo a curettage surgery.
