Hello, in general, the embryo tissue is usually discharged in 4-6 hours on the fourth day after the drug is taken, that is, after the last drug is taken. Generally, after the blood clot is discharged, the abdominal pain gradually stops and the amount of bleeding is greatly reduced. But whether it is completely discharged or not needs to be identified. Exclusion of intact embryonic tissue is the success of abortion. It is very important to identify the outflow blood clot. We should pay attention to the following two points: 1. If the drug flow is not clean, there will be nausea and greasy feeling, as well as symptoms such as abdominal pain and persistent vaginal bleeding. You should immediately go to a regular hospital for gynecological examination and B-ultrasound examination. 2. If the drug flow is not clean, infection will occur. If the B-ultrasound judgment is that there is no residue in the uterus, then the infection in the uterus should be considered, because the blood produced by abortion is a good culture base for bacteria. If the medicine flow is not clean, there will be tenderness in the uterus during gynecological examination, and there will be symptoms such as fever. Moreover, in recent years, there have been many cases of infertility and gynecological inflammation caused by unclear drug flow, so if it is found that the drug flow is unclear, it is necessary to go to the hospital for clear palace surgery immediately. Otherwise, the residual fetal membrane tissue will cause blood collapse and even life-threatening. Finally, I wish your friend a speedy recovery.
